alphablending

I'm new at OpenGL and I can't find out how to do this:
I want to render a letter and be able to change it's color, so I have a texture with the letter on a transparent background. I managed to render it using this code:

glEnable(GL_BLEND)
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA)

But that renders the letter in black, as it's on the texture. How can I render it with the color setted with glColor4f?
