changing truck color?

[terp]

I tried to change truck color to white, had no luck. I did okay with brown, black but no yellow, or white. What am
I doing wrong? thanks terp hey I got the brush to work.

That's because white is basically not a color and neither is black. If you want to change it to white then you need to desaturate it and pump the lightness up with any tool(s) you prefer.
