RGBA color space
RGBA color space stands for Red Green Blue Alpha.
The alpha channel is the transparency channel, and is unique to this color space.
RGBA, like RGB, is an additive color space, so the more of a color you place, the lighter the picture gets.
PNG is the best known image format that uses the RGBA color space.
