I fear that possibly my earlier question was perhaps not too clear. To
review:

Yes...

[Raney:]
There's no fixed boundary here, though remapping 24-bit color images
down to 8-bit is no walk in the park.

In actual fact, I DO NOT want to operate with 8-bit colours. I want to
operate in/with 24-bit. The 255 colours thing was just fiddling.

(Also JPG is out, BMP is in.)

So, any idea why my skin is blue, and how it may be remedied?
