lightmap is a data structure used in
lightmapping, a form of
surface caching in which the brightness of surfaces in a virtual scene is pre-calculated and stored in texture maps for later use. Lightmaps are most commonly applied to static objects in applications that use real-time 3D computer graphics, such as video games, in order to provide lighting effects such as
global illumination at a relatively low computational cost.

Why are normal maps blue
Only tangent space normal maps are primarily blue. This is because the colour blue represents a normal of (0,0,1) which would be an unchanged normal when the triangle lies in the plane x and y, i.e. perpendicular to the surface.
Normal vectors in a normal map are expressed in tangent space where normals always point roughly in the positive z direction (means that vector N is close to 1, T and B are close to 0).
Why are normal maps blue and purple in color?
