When I create four random colors, a and b show up as a row of four swatches But when I try to create a matrix [a;b], figuring four over and under, all I get is a vector row of eight swatches What am I doing wrong? a = [RGB(rand(),rand(),rand()) for x in 1:4] b = [RGB(rand(),rand(),rand()) for x …

Why don't I get a matrix of colors instead of a vector?

Thanks. What is the apostrophe for? I haven’t seen that usage.
