In order to render fonts in opengl, I render a set of textures at startup each containing a separate glyph render white on black. my problem is that i want font colors also. of course i cannot render a set of textures in each conceivable color i would want to have text in. my question is, how can i achieve the capability to render my font textures in a different color than from what they are drawn in the textures e.g. my textures are white but i want to draw text in red. what opengl texture parameters do i need to set to achieve this.
