OpenGL OpenGL: Basic Coding

Hi everyone:
How are you! Could you please give me some idea.
I use this :#define glRGB(x, y, z) glColor3ub((GLubyte)x, (GLubyte)y, (GLubyte)z)

But I still change drawing color anywhere.

You already posted this.
You probably didn’t get a response because you
aren’t really making sense.

can you try and explain your problem a little bit
more.
