What do the colors in a normal map mean?
One of the most valuable maps for a 3D artist is the normal map. Rather than having a color range of black to white, like a bump map uses, normal maps consist of red, green, and blue. These RGB values translates to x, y, and z coordinates, allowing a 2D image to represent depth.
What does the color purple in the map indicate?
Black: roads, railroads, highways, bridges, place names, buildings, and borders. Purple: highways, and on U.S. Geographical Survey topographic maps, features added to the map since the original survey.

Why is normal map all blue and sometimes only the UV parts?
Also, your render will come out with that bluish purple color if you don’t uncheck color and check normal in the textures panel. Once you do this, it will just create the illusion of depth and keep the color whatever you set it at. Ryeath(Ryeath)
Which is the most common color in normal mapping?
Hence the parts of object directly facing the viewer are light blue. The most common color in a normal map. A normal pointing to top right corner of the texture (1,1,0) is mapped to (255,255,128). Hence the top-right corner of an object is usually light yellow.
Why do normal maps look like texture maps?
Normal maps look strange, but like any other texture map, they are just flat 2D images. Here’s a close-up shot of a 3D bird character. To the right is a close-up of the bird’s normal map. The highlights and shadows on the bird’s feathers are being created by the patterns in the normal map.
Why do normal maps fake shadows and reflections?
Normal maps have a huge impact on the way objects are presented because normal maps don’t just fake shadows. Rather, they fake how light behaves on a surface, so that includes reflections.
