CSSColor accepts CSS Color Level 3 colors. In level 3, the Hue has to be a pure number (with the implicit unit degree). if you change the first 50% to, say, 90, then isValid will return true.

Well, but even when I look at CSS Color Level 4, I can't make any sense of a percentage hue value (e.g. 50%):

Hue is represented as an angle of the color circle (the rainbow, twisted around into a circle, and with purple added between violet and red).

<hue> = <number> | <angle> | none

Because this value is so often given in degrees, the argument can also be given as a number, which is interpreted as a number of degrees.

So IMO CSSColor behaves a documented (but limited to CSS Color Level 3).
