Create RGB Color Object

Description

Allows conversions to: CIELAB, CIELUV, CIEXYZ, HLS, HSV, hexcols. polarLAB, polarLUV and sRGB.

Usage

RGB(R, G, B, alpha=None)

Arguments

Rint, float, list, numpy.array

Numeric value(s) for red intensity ([0., 1.]).

Gint, float, list, numpy.array

Numeric value(s) for green intensity ([0., 1.]).

Bint, float, list, numpy.array

Numeric value(s) for blue intensity ([0., 1.]).

alphaNone, float, list, numpy.array

Numeric value(s) for the alpha channel ([0., 1.]) where 0. equals full transparency, 1. full opacity. If None (default) no transparency is added.
