What is the best background color for a diffuse texture ? Most of them have a black background color, but why not white or something else ? Skin and hairs looks like the best on white. Blue is the best for Photoshop masking because this color is the most rare in character texture but it looks funky. What do you think ?
The only place it actually matters is for sections of a texture that use alpha maps, such as foliage, hair, fur etc... The best background for these is the color of whatever is being masked, so green blades of grass would look best on a green background, red hair on a red background etc... This avoids those blacks or white…
