PostCSS Gamut Mapping lets you use wide gamut colors with gamut mapping for specific displays following the CSS Color 4 Specification.
When out of gamut colors are naively clipped the result can be radically different.
A saturated and bright color will be much darker after clipping.
To correctly adjust colors for a narrow gamut display, the colors must be mapped.
This is done by lowering the chroma
in oklch
until the color is in gamut.
Using the @media (color-gamut)
media feature makes it possible to only use the wide gamut colors on displays that support them.
p {
background-color: oklch(80% 0.05 0.39 / 0.5);
color: oklch(20% 0.234 0.39 / 0.5);
border-color: color(display-p3 0 1 0);
}
