Colors over my textures ingame

[Limpet]

Some of my textures ingame get funny color overlays ingame. I'll have big squares of different colors sometimes. For example. I have a brush with a texture of a door on it, in game you can tell its a door but its purple. Earlier when I was building a room the floor and ceiling did the same thing but with more colors.

Why does this happen?

i think taht happent because they are reflective surfaces- make a cubemap near them and type "buildcubemaps" in console

close hammer, close sdk, close hl2, open hl2, go see your map.
