Does CSS support deep (30/36/48-bit) colors?

Answer 1

Hello,

CSS itself is not related to color depth, so basically the answer to your question is: N/A.

FWIW, to represent Black, the CSS color property supports the following formats:

1. RGB (0, 0, 0)
2. RGBa (0, 0, 0, 1)
3. HEX (#000 or #000000)
4. HSL (0, 0%, 0%)
5. HSLa (0, 0%, 0%, 1)
6. Named-color (black)

There are these other values of the color property although not specifically for Black, these properties work for any color:

1. Keyword value (currentcolor)
2. Global values (inherit, initial and unset)

More information about the CSS color property on Mozilla Developer Network (MDN): https://developer.mozilla.org/en-US/docs/Web/CSS/color

Hope this helps.
