Constructor pattern.

opac

set opacity

interpolate between 2 colors

interpolate across a list of Colours, with input being in Range 0 1

>>> blends 0 [black, (Colour 0.2 0.6 0.8 0.5), white] == black
True

>>> blends 1 [black, (Colour 0.2 0.6 0.8 0.5), white] == white
True

>>> blends 0.6 [black, (Colour 0.2 0.6 0.8 0.5), white]
RGBA 0.16 0.48 0.64 0.60

convert from Colour to #xxxxxx
