[Graphics] Porting Vanilla Red/Blue colors to Yellow version?

Hi,

I know Yellow is already in color, but it is colored like the SGB palettes of Red and Blue rather than in full color like the Vanilla/Gen 2 hacks. My question is this; is it possible to port the full colors to Yellow, or to Red/Blue with another language like French? Yellow is my priority... if it can be done, of course. Thanks!

IDK if you are still around, but I'll answer since nobody else seems to ever answer questions about Yellow.
There is a Full Color hack of red/blue. You can try looking at how they do it and try to port the changes to Yellow, but I warn you, I looked and it looks very tedious. I might give it a try someday despite that.
