Steps to reproduce:

Toggled the pref layout.css.more_color_4.enabled to get access to the new colour notations.

Actual results:

While the new notations certainly work, out-of-gamut colours are wildly wrong. It appears that the displayed colours are simply clipped to the RGB range.

Expected results:

Colours outside the sRGB gamut should be mapped using CSS gamut mapping as specified in CSS Color Module Level 4.

Hi Tiaan, would you mind checking this bug?

Right now we are not mapping out of bounds colors. They are indeed just clipped. Gamut mapping is tracked in bug 1626624.

Marking this one as a duplicate.
