How do I change the color of a texture in BGE? I’ve played around with material and texture settings and nothing is doing the trick…the object I want to apply color to is a text object just so you know.
There are 2 methods:
Vertex Paint - paint the vertices of your mesh the desired colour (using an opacity 1.0 brush and cover all verts, then select Vertex colour or vertex light in the material tab, and make sure your texture is not set to map the objects colour, for text, you still need to keep the alpha. This can be animated using a small script to access the vertex colours of each vertex, allowing advanced animation and superior control, the other method is harder, more glitchy and offers less control, so i’ll inform you of it’s existence, but not go into detail pointlessly…
Ipo curves
IPO Curves: YOU DARE SPEAK THAT LANGUAGE HERE!! O_O
Yeah, it’s F-Curve, now, Haker. LOL
Actually, you can also use obj.color to switch the material color using Python. It’s not that hard.
I’m guessing obj.colour is in 2.5 since everything is moving from methods to attributes? I use 2.49 still; I’ll move when I’m done with my current project… 
Keeping it old sKool… :o
