Could someone explain what the colors are that we see in baking modes? Is there a significance to this purple color in normals baking mode? And derivative is a sort of lime green.

The three colors represent the x, y, z normal vectors.
Normal maps usually are used to fake a high resolution mesh on what is actually a low resolution mesh. The color values in the normal map control what direction each of the pixels on the low-poly model would be facing.
