matplotlib.colors.to_rgba

matplotlib.colors.to_rgba(c, alpha=None)[source]

Convert c to an RGBA color.

Parameters:
c : Matplotlib color
alpha : scalar, optional

If alpha is not None, it forces the alpha value, except if c is "none" (case-insensitive), which always maps to (0, 0, 0, 0).

Returns:
tuple

Tuple of (r, g, b, a) scalars.
