   multiple texture, multiple color
  OpenGL can support multitexture rendering.. but is it possible to specify different color for each texture?There seems to be only glColor.. and I'm trying to avoid drawing things twice because the particular chip (PowerVR MBX for iPhone) I'm working on says multitexture is much better than multipass rendering (I think that's what it's called) in terms of performance.So yeah, is there an ARB extension or anything like that?   
  Are you wanting to modulate the texture with a colour? In which case, there is way to do this in standard OpenGL. However, you can do this very easily using Shaders.   ;  Yeah, but different colours for each texture. Also, no access to shader.. I'm stuck under OpenGL ES 1.1 :/Yeah, it's an iPhone game ;)   ;  There is GL_TEXTURE_ENV_COLOR for each texture unit.This page makes use of the alpha just to do an interpolationhttp://www.opengl.org/wiki/Texture_Combiners
