Color.from_string
Description:
Parses a string definition of a color, filling the red,
green, blue
and alpha fields of color.
The color is not allocated.
The format of str can be either one of:
- a standard name (as taken from the X11 rgb.txt file) - 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.
