PHP Класс SassColour

Provides operations and type testing for Sass colours. Colour operations are all piecewise, e.g. when adding two colours each component is added independantly; Rr = R1 + R2, Gr = G1 + G2, Br = B1 + B2. Resulting colours are returned as a named colour if possible or #rrggbb. Transparent is a SassColour. Operations on transparent return transparent.
