Is there a way to get the pixel color for a position in a tile of a TMXTiledMap ?

Byte pixelColor[4];
glReadPixels(x,y, 1, 1, GL_RGBA, GL_UNSIGNED_BYTE, &pixelColor[0]);

I'm in the process of writing a general color picker node to submit to the cocos library, but if you know OpenGL you can just use this.

Thanks, but isn't this only for the pixel at that position in the framebuffer, as it doesn't work for me.

Also looking for this, anyone know how to read the pixel color at a location on a tile from a TMX map?

You could get the sprite of the tile, load it into a mutable texture and read out the color value.
