For testing I modified the swapping macro from include/swap.h (to not do any swapping). It has no impact on the colors on the framebuffer screen. I grep'ed over the complete code and did not find a place where wswap is used to swap any access to the framebuffer. The swapping macros are only used when handling .bmp images. For further testing I wrote a little tool that maps the framebuffer memory and runs over every pixel, does a 16bit read, swaps the pixel and writes it back. In the end my colors look as expected. So it's definetely a swapping issue.
