For example, there is a lighting switch and its icon. If switch is ON icon should be yellow, otherwise it should be black. But in real device icon every time is pink. I suspect that something wrong with pixels coloring using SDL. There is a method OrbiterRenderer_SDL::ReplaceColorInRectangle in the OrbiterRenderer_SDL.cpp which changes colors of icons. Maybe SDL for nokia 770 uses different color format for pixels?
