Thx Shiela - yeah it increases the colours a bit too :) These are not manipulated before hand so lots of possibilities with a bit of postwork. You had me really curious then as to why you wanted that bit in particular :D

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
