White
The materials white0## are used to create texlights, textures that emit light in games. They are located in the HL2 folder:
materials\lights
It's recommended to match the color of your texture with the light emitted defined in light.rad, unless you are looking for an effect, like a red wall that emits blue light.
To customize the colors emitted by the white0## materials, you can locate them in the light.rad of HL2.
