The plane itself should have no color. Did this occur when you attempted to use your own texture? Can you post the code you are using?

I think that you're going to need to enable blending ..

glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);

Try adding those lines before the call to glActiveTexture()
