Add this to MediaWiki:Wikia.css:

/* Colour code of Recent changes page byte difference indications */ .mw-plusminus-pos { color: #99FF33; } .mw-plusminus-neg { color: #FFAD99; }

They should be self explanatory, but "pos" is the + (green) and "neg" is the - (red). You can replace what's next to colour with basically any colour you want. I've given you CS Wiki's for now.
