Implement a mechanism that allows us to alter colors so that they mimic those a colorblind person would see. From the color we can then alter the colors for the whole preview so we can simulate everything in the theme including icons/decorations. This filter is also available as a Filter in LibGfx so it can be reused in multiple other places. The color simulation algorithm is based on this one https://github.com/MaPePeR/jsColorblindSimulator publicly available.
