(...) in PhotoShop or GIMP or PSP, an RGB value stays an RGB value, and should not shift when painting or filling or whatever.

Exactly, it should not...

Alas, it doesn't address those colors correctly... hence this post. :wink:

See agracier, my main concern was not how do I make a map. It was something more in the lines of I'm using photoshop, I've painted 31, why does it read 32... must be anti-aliasing... no, it must be the layer mode... after many musts, I decided to check if anyone else using photoshop could confirm the shift.

then...

fabianfred has pointed that earlier versions of PS had this problem and the PS CS4 may work fine.

... and yes, just like you, I find it very surprising when things happen that should not.

If I find out more, I'll share the info.
