Do you care what color each box ends up being?
You’d have to calculate a mask based on modulo math. If R%5==2, you’re in the middle column. If G%5==1, you’re in the next-to-bottom row. If both of those are true, then multiply your squares by the color you want in the middle-column-almost-bottom box.
On the right track. Drag a line from Split’s R to the top of your Modulo, not the output of Fraction.
Still not work:( I got the idea, but I don’t understand how to implement it. After modulo comparison result always false.
@halley1 Thanks for help! I found another way. Maybe it will be useful for someone.
