What would cause textures to be rendered with a red tint?
Mismatched byte order? RGBA / ARGB / BGRA?
I had the same type of problem with my program to, but then I realized that the color of the polygon beneath the texture was red, check what color the polygon is drawn in, if it’s red gl.glColor3f(1.0f,0.0f,0.0f) then just change it to white gl.glColor3f(1.0f,1.0f,1.0f)
