Cannot change color ☹ – Drawing with Carl Review

Hi! This app is really great and fun to use. I LOVE it, but there's just one problem. When ever I try to draw something, no colors are there for me to select. I can only use red, and there is still no line of colors. I can pick the brushes I use, but not the colors. I don't have full version. P.S good job fixing the marker bug!
