it’s actually easier than you’d think! On the left side of every black ‘square’ (they’re not rly squares but u get the point), I painted a line of red and a line of yellow to the left of the red, then on the right side of every black square, I did a line of blue. Which colors go on which side doesn’t really change the effect though, as long as it’s consistent and the red/yellow are in the right order (with yellow on the outside).
