How to create a multi-color square grid in OpenGL ES 2.0?

Question

Using Open GL ES 2.0, I want to create a large grid of squares where each square can take on a specific color defined by a definition file. So this is not a simple chessboard with only black and white squares ...
What is the best way to do this to avoid artifacts?

Thanks in advance

Answer 1

There is nothing that indirectly causes artifacts when drawing a grid of squares. There are no inherent problems with z-wrestling, depth or transparency, as described in this question.
