I wonder whether we should allow constructing ColorValue with supported color keywords. Or is there any existing function to do so?

@shans would have a better answer to that?

interface CSSColorValue : CSSStyleValue{
readonly attribute double r;
readonly attribute double g;
readonly attribute double b;
readonly attribute double a;
};

{{CSSColorValue}} objects represent values of the 'color' CSS data type. {{CSSColorValue}}s are
initialised using the RGB cubic-coordinate system, which specifies a red, green and blue
component. These are specified as doubleegers between 0 and 255. An alpha component may also be
specified in the constructor as a double between 0 and 1.

Issue: Do we want to support other color systems, e.g. HSL?
