I also made some local changes to tcx.c today to avoid having a blue-

functions should be merged with vga.c (where they are being patched
by Q) - should I provide a qemu patch doing this and fixing the issue
for both? Or is this for some reason restricted to Q?

I made a patch to fix both vga and tcx while also unifying the pixel
operations, does it fix the blue foot disease on PPC?

Hm, _with_ this patch I get (on PPC/Linux, emulating LE MIPS):
 - a blue-footed penguin when the cirrus FB is started
 - blue instead of red colour in console output
 - A general blue-to-red inversion for X11 in 16bit mode.

Note that the colours for the last one were already not quite right
(e.g. grey became a pale blue), but with your patch it looks even

I haven't been able to test the new patch yet.

Q's patch and my adaptation for tcx just reversed the order of the colors, just like BlueSwirl's patch except that they used #if __LITTLE_ENDIAN__ in place of #ifdef WORDS_BIGENDIAN, and this worked for both i386 and sparc32 guests on i386 host (but is not applied for ppc host).
