Decided to make some Christmas gradients by importing the images into Visions of Chaos software and creating palettes from there, the software allows more control over how it processes the colours it finds, which allowed a finer control over what came out.
Find your gradients folder, and unzip this package in there. Then start your JWildfire and look for Christmas MB in the gradients folder.
There's 40 in total, but some are just variants of each other. There's enough to play with anyway. Merry Christmas!
