About
Package xcolor implements Red, RedGreen, and RGB color models matching the core image/color interface.
Note that there are good reasons these color types aren't in the core image.color package. The native color types may have optimized fast-paths for many use cases.
This package is a tradeoff of these optimizations against lower memory usage. This package is intended to be used in computer graphics (e.g. OpenGL) where images are uploaded to the GPU in a specific format (such as GL_R, GL_RG, or GL_RGB) and we don't care about the performance of native Go image manipulation.
