Yeah, I know what went wrong, but no matter how hard you try, colour  
is always different. Its not science, its gut feeling

I may have them the wrong way around. When I make colour images for  
the gallery (my hallway!!!) I always make them in one batch so the  
"flavour" stays the same for the whole exhibition. Mixing colour  
images is very difficult, and so I leave that to Helen ;-)
