I know there are some functions in PHP for setting alpha blending and such,
found here: http://se2.php.net/manual/en/function.imagealphablending.php

However I can't find a way to set HUI on a picture thru PHP?

What i'm really looking for is a way to somehow apply a selected colour
to a monochrome image.. Making it blue-ish, or red-ish.. och whatever.. -ish there is..

Think monochrome..

Don't point me in a direction of a complete library, I only need this one function.

Thanks in advance!
