I don't know the complete answer to your predicament off the top of my head, but it sounds like you are leaving out some steps for deciding the final color: a review of the famous "Red Book", chapter 4 & 5, the latter of which makes the highly relevant observation, "Part of this computation [final pixel color] depends on what lighting is used in the scene and on how objects in the scene reflect or absorb that light"
Note the word 'part'; it takes more than just the combination of Lightfy and Materialfy to set the final color. The Red Book is at http://www.glprogramming.com/red/. I know the edition is quite old, but it turns out to be quite up to date for the version of Open GL (1.3) assumed by OpenGL ES 1.x.
