That won't be hard. Lots of people here LOVE black dollars, and you can use just about any color for your frac. So make that green. Then use a $20 instead of a $25 for your upper denom. I prefer using $20s in lower stakes games and like using yellow or purple. Also no reason your $5 has to be red if you don't care for red chips. Pink, orange, brown, or blue are fine. It's your set. Use the colors and spots that YOU want. No need to bow to convention.
