I''ve adapted the Nehe code for bitmap fonts into my application. The basic font rendering works beautifully (thanks!), and I can control the transparency of the text using the alpha channel. Is it possible to change the colour of text? I tried:

  			glEnable(GL_BLEND);
			glBlendFunc(GL_SRC_ALPHA,GL_ONE);
			glColor4ub(255, 0, 0, 200);

before rendering the text, but it doesn''t affect the text colour at all. Is this possible? Thanks

Try using glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA) instead.
