an hexadecimal value in the form: #rgb, #rrggbb, #rgba, or #rrggbbaa
a RGB color in the form: rgb(r, g, b)
a RGB color in the form: rgba(r, g, b, a)
a HSL color in the form: hsl(h, s, l)
-a HSL color in the form: hsla(h, s, l, a)
where 'r', 'g', 'b' and 'a' are (respectively) the red, green, blue color
intensities and the opacity. The 'h', 's' and 'l' are (respectively) the
hue, saturation and luminance values.
In the rgb() and rgba() formats, the 'r', 'g', and 'b' values are either
integers between 0 and 255, or percentage values in the range between 0%
and 100%; the percentages require the '%' character. The 'a' value, if
specified, can only be a floating point value between 0.0 and 1.0.
In the hls() and hlsa() formats, the 'h' value (hue) is an angle between
0 and 360.0 degrees; the 'l' and 's' values (luminance and saturation) are
percentage values in the range between 0% and 100%. The 'a' value, if specified,
can only be a floating point value between 0.0 and 1.0.
Whitespace inside the definitions is ignored; no leading whitespace
is allowed.
If the alpha component is not specified then it is assumed to be set to
be fully opaque.
