alright... so say you have two completely different colors that you want to anti-alias, but you dont want/cant to figure out which colors to use yourself. o jeez, im in a bit a pickle, right? wrong. open up GM, have some notes (saying the HSL of the two colors) or just leave open ur image editor so you can go back for reference on the HSL. so make a new sprite in GM, go to edit. create a new size only 1 px high, depending on how many AA colors you want differs your width. no matter how many colors you want to AA with, always add to more pixels (3 AA colors+ 2 base colors, now you have 5, put 5 in the width box). now go in the image editor, and press gradient fill. choose your two base colors, and choose the horizantal one. press ok, now u have your 2 base colors on either end and the colors to AA with in between.
btw i just figured this out.
tell me if i need to reword this.
That sounds like a good idea i might want to try it.
