As David Dorward noted, those two color values are not valid per CSS2.1
[1]; the W3C's CSS validator validates against CSS2.1 by default.

The values /are/ valid CSS3 (CSS3 Color) [2]; if you want to validate
against CSS3, you need to click "More Options" then, in the Profile
drop-down, select "CSS level 3".

[2] CSS3 Color Section 4.3 SVG color keywords:
