``rgbi:<red>/<green>/<blue>``
red, green, and blue are floating-point values between 0.0 and 1.0, inclusive. The input format for these values is an optional
sign, a string of numbers possibly containing a decimal point, and an optional exponent field containing an E or e followed by a possibly
signed integer string.
sign, a string of numbers possibly containing a decimal point, and an optional exponent field containing an E or e followed by a possibly
signed integer string. Values outside the ``0 - 1`` range must be clipped to be within the range.
If a color should have an alpha component, it must be suffixed to the color
specification in the form :code:`@number between zero and one`. For example::
red@0.5 rgb:ff0000@0.1 #ff0000@0.3
The syntax for the floating point alpha component is the same as used for the
components of ``rgbi`` defined above. When not specified, the default alpha
value is ``1.0``. Values outside the range ``0 - 1`` must be clipped
to be within the range, negative values may have special context dependent
meaning.
In addition, the following color names are accepted (case-insensitively) corresponding to the
specified RGB values.
