In line with Toshi Omagari, the creator of Arcade Recreation Typography, the world’s first multi-colored digital font was created in 1982 for a never-released online game known as Insector. Multi-colored fonts, generally known as chromatic sort, are nonetheless comparatively uncommon on the net, though the COLR font format has had full cross-browser assist since 2018 (even in Web Explorer!).
The know-how opens up a wholly new vein of typographic creativity. Whereas a number of the coloration fonts I’ve seen have been lurid, at finest, chromatic fonts are enjoyable, progressive and attention-grabbing. With each the addition of a brand new CSS options — together with the font-palette property and @font-palette-values rule — for controlling the colour palette of coloration fonts and the evolution of the COLR font format, it’s a good time to dive in and experiment with with what trendy internet typography can do.
COLR assist
I final wrote about coloration fonts in 2018. On the time, there have been 4 totally different requirements for multicolored typefaces: OpenType-SVG, COLR, SBIX, and CBDT/CBLC. You should utilize ChromaCheck to see what coloration font codecs your individual browser helps.
Google Chrome has marked OpenType-SVG as “wontfix” which means that format won’t ever be supported by Chrome or Edge. SBIX and CBDT/CBLC can principally be ignored to be used on the net as they’re each based mostly on raster photographs and develop into blurry at bigger font sizes. The massive file dimension of bitmap-based fonts additionally makes them a nasty alternative for the online.
Ulrike Rausch is the creator of LiebeHeide, a bitmap coloration font which uncannily replicates the look of a ballpoint pen. “My largest objective was all the time to breed handwritten textual content as authentically as attainable,” she advised me. “For LiebeHeide, I used to be lastly capable of simulate these handmade attributes with a font. The draw back? All of the PNG photographs within the font file add up and end in an unlimited OTF file dimension. This won’t be an issue for desktop purposes, like Adobe InDesign, however to be used on the net the font is hardly relevant.”
All browsers assist COLR fonts (now typically known as COLRv0). Model 98 of Chrome (and Edge), launched in February, added assist for COLRv1, an evolution of the format.
This browser assist knowledge is from Caniuse, which has extra element. A quantity signifies that browser helps the characteristic at that model and up.

COLRv0 and COLRv1
Plakato from Underware foundry
COLRv1 is a part of the OpenType 1.9 customary. Whereas the preliminary COLRv0 lacked most of the inventive potentialities of OpenType-SVG, COLRv1 matches these potentialities whereas avoiding sure drawbacks. COLRv0, for instance, may solely do stable colours whereas COLRv1 can do linear, radial, and conic gradients. The format additionally provides compositing and mixing and permits for form reuse to save lots of on file dimension.
Typography professional Roel Nieskins explains: “I used to say the OpenType-SVG format was one of the best format because it provided probably the most versatility — till I noticed that is simply too advanced for a low-level job like textual content rendering. It implements a primary subset of SVG on the font rendering degree. Nevertheless it doesn’t work nicely with different font tech (hinting, variable axes, and so forth.), and it’s a ache to implement. So, I switched sides to COLR. COLR mainly re-uses all the things that OpenType fonts have already got. It ‘solely’ provides layering, and the chance to vary the colour of every layer. Easy, however efficient.”
COLRv1 is solely suitable with variable font axes, and there are already examples of variable COLR fonts like Benefit Badge, Plakato Coloration and Rocher Coloration.
Right here’s a hanging instance from Ulrike Rausch of what’s attainable with the format, a (at present unreleased) typeface which digitally recreates the look of a neon signal:
Akiem Helmling of the kind foundry Underware is enamored with COLRv1, telling me that “[t]he COLRv1 format can doubtlessly have an identical (and even greater) affect on sort design than variable fonts had lately.” For Akiem, it’s undoubtedly the superior format. “All former coloration codecs have been dangerous hacks so as to add colours to glyphs. Whereas OpenType-SVG is regarded by some folks as a superb resolution, it’s, from my standpoint, in no way. From a practical standpoint, SVG is a ‘locked room’ inside the open construction of OpenType. There isn’t a solution to re-use or hyperlink knowledge or to create a connection between different font tables and the SVG desk. And due to this, we can’t make a variable font with variable SVG knowledge.”
It’s nonetheless early days for the format. Mozilla hasn’t but shipped COLRv1 however has taken a constructive place on the format, stating that it has “the potential to supersede OpenType-SVG fonts in internet use.” Apple is reluctant to implement it in Safari.
COLRv1 fonts will nonetheless present up and be readable in these browsers however all of the letter’s can be a single stable coloration (which you’ll be able to set with the CSS coloration property, similar to with a traditional font). We’re but to see many sort foundries launch COLRv1 typefaces, and a few widespread design instruments like Figma don’t even assist COLRv0, however I’m hopeful and consider it will likely be the way forward for coloration typography on the net. Within the quick time COLRv1 has been round there have already been some lovely examples of what the know-how can do, comparable to Reem Kufi and Bradley Initials.
COLR and CSS
In the event you’re utilizing a coloration font, you in all probability need to have the ability to management its colours. Till now, that was inconceivable to do with CSS. The font-palette property brings the facility to override the default coloration scheme of a typeface and apply your individual. This property works on COLRv0 and COLRv1 typefaces. (Apple’s Myles Maxfield explains that SVG fonts can opt-in to utilizing palettes, whereas all the colours of a COLR typeface are robotically overridden by CSS.)
Arising with a good coloration palette is a high quality artwork. Some sort designers have accomplished the laborious work for us and embrace different palettes contained in the font. You possibly can choose from these totally different coloration schemes utilizing base-palette in CSS.
How do you discover out if a font provides an alternate palette? The positioning for the font may inform you. If not, there’s a helpful software known as Wakamai Fondue that may checklist all of the obtainable coloration schemes (proven within the picture beneath). For this instance, I’ll use Rocher Coloration, a free variable coloration font from Henrique Beier with a Flintstones vibe. From Wakamai Foundue we are able to see that this typeface makes use of 4 colours and comes with eleven totally different palette choices.
Utilizing base-palette: 0 will choose the default coloration palette (within the case of Rocher, that’s shades of orange and a brown).
Utilizing base-palette: 1 will choose the primary different palette outlined by the creator of the typeface, and so forth. Within the following code instance, I’m choosing a coloration palette that’s totally different shades of grey:
@font-palette-values –Grays {
font-family: Rocher;
base-palette: 9;
}
When you’ve chosen a palette with the CSS @font-palette-values rule, you’ll be able to apply it utilizing the font-palette property:
.grays {
font-family: ‘Rocher’;
font-palette: –Grays;
}
After all, you may wish to create your individual palette to match your model colours or to fulfill your individual design sensibility. In the event you’re going to override all the colours then you definately don’t must specify the base-palette.
Let’s take Bungee from pioneering sort designer David Jonathan Ross for example. It solely makes use of two colours by default, crimson and white. Within the following instance, I’m overriding each colours of the font, so the base-palette doesn’t matter and is omitted:
@font-palette-values –PinkAndGray {
font-family: bungee;
override-colors:
0 #c1cbed,
1 #ff3a92;
}
@font-palette-values –GrayAndPink {
font-family: bungee;
override-colors:
0 #ff3a92,
1 #c1cbed;
}
Alternatively, you’ll be able to set the base-palette as a place to begin and selectively change simply a number of the colours. Beneath I’m utilizing the grey coloration palette of Rocher, however overriding one coloration with a minty inexperienced:
@font-palette-values –GraysRemix {
font-family: Rocher;
base-palette: 9;
override-colors:
2 rgb(90,290,210);
}
physique {
font-family: “Rocher”;
font-palette: –GraysRemix;
}
When specifying override-colors it’s troublesome to know which little bit of the font can be overridden by which quantity — you need to mess around and experiment and obtain the specified impact by trial and error.
Must you want, you’ll be able to even change the colour of emoji fonts, comparable to Twemoji (proven beneath) or Noto. Right here’s a enjoyable demo from a font engineer at Google.
Present limitations
One regrettable limitation, at the very least in the intervening time is that CSS customized properties don’t work in @font-palette-values. Which means the next is invalid:
@font-palette-values –PinkAndBlue {
font-family: bungee;
override-colors:
0 var(–pink),
1 var(–blue);
}
One other limitation: animations and transitions from one font-palette to a different don’t interpolate — which means you’ll be able to change immediately from one palette to a different, however can’t steadily animate between them. My dream of a luridly animated emoji font is unfortunately unrealized.
Browser assist
font-palette and @font-palette-values have been supported in Safari since model 15.4, and landed in Chrome and Edge with the discharge of model 101.
This browser assist knowledge is from Caniuse, which has extra element. A quantity signifies that browser helps the characteristic at that model and up.

Use instances
You possibly can in all probability already think about the way you may use coloration fonts in your individual tasks. There are a few particular use instances, although, which can be value calling out.
COLR and icon fonts
Icon fonts could now not be the most well-liked methodology for displaying icons on the net (Chris explains why) however they’re nonetheless extensively used. In the event you use an icon font with a number of colours, like Duotone from FontAwesome or the two-tone icons from Materials Design, font-palette may provide a neater methodology for personalization.
Fixing the emoji downside
Nolan Lawson not too long ago wrote concerning the issues of utilizing emoji on the net. The Chrome developer weblog explains one moderately advanced present resolution:
In the event you assist person generated content material, your customers in all probability use emojis. Immediately it’s quite common to scan textual content and substitute any emoji encountered with photographs to make sure constant cross-platform rendering and the power to assist newer emojis than the OS helps. These photographs then must be switched again to textual content throughout clipboard operations.
If it receives larger browser assist, COLRv1 emoji fonts will provide a far easier method. COLRv1 additionally comes with the good thing about trying crisp at any dimension, whereas native browser emojis get blurry and pixelated at bigger font sizes.
Wrapping up
Earlier than coloration fonts, typographic creativity on the net was restricted to making use of strokes or gradient fills with CSS. You might all the time do one thing extra customized with a vector picture, however that’s not actual textual content — it may well’t be chosen by the person and copied to the clipboard, it may well’t be searched on the web page with Command+F, it isn’t learn by display screen readers or serps, and also you’d must open Adobe Illustrator simply to edit the copy.
Coloration fonts have the potential to essentially seize a person’s consideration, making them good for touchdown pages and banners. They is probably not one thing you attain for sometimes, however they promise new expressive and inventive potentialities for internet design that may make your website stand out.
