When color picking the map color of the transport belt, I get #ce9e42. This can be converted to r: 0.80, g: 0.62, b: 0.26 which is different from ["transport-belt"] = {r = 0.8, g = 0.63, b = 0.28}, which is defined in data/core/prototypes/utility-constants.lua. The same can be done for all other map colors, each will yield slightly different color offsets.

Map uses 16bit color format (RGB565) to save memory, so it has precision 0.03125 on red and blue channel and 0.015625 on green channel. In binnary/hex format it means tree (two) lowest bits are lost from RB (G)
