I need to disable all options that could manipulate the pixel color. What kind of options is this?

I'm not quite sure what you mean... pretty much everything in OpenGL manipulates pixel color in one way or another. If it didn't, it wouldn't be much use as a graphics API.
Even drawing a simple app that draws a triangle is going to manipulate the pixel color at the location where you draw the triangle. Hell... even a glClear(GL_COLOR_BUFFER_BIT) is going to manipulate the pixels by setting them to the current clear color.
deiussum is correc, perhaps you wanna use someit like glTexEnvi( GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE );
replace means the pixels colour will ignore the previous pixels colour
