Wide Gamut Color in CSS with Display-P3

Here’s something I’d never heard of before: Display-P3 support in CSS Color Module Level 4 spec. This is a new color profile supported by certain displays and it introduces a much wider range of colors that we can choose from.

Right now the syntax looks something like this in CSS:

header {
  color: rgb(0, 255, 0); /* fallback color */
  color: color(display-p3 0 1 0);
}

It looks weird, huh? Over on the WebKit blog, Nikita Vasilyev shows how we can see these new colors in Safari’s DevTools:

Back in 2016, Dean Jackson wrote about improving color on the web and why Apple is interested in this much wider color gamut. The general idea is that more accurate colors make for a better and more vibrant user experience.

Also, it looks like all this is only available in Safari right now.
