Feature doesn't work – Jazza's Arty Games Review

I wanted to use the color challenge, but the app defaults to one color and will not let me select anything else. I saw Katvalk use it for a 5 color challenge and was inspired to try it, but it will not work. Also many of my Promarkers are not in the list for selection, I wish their was a way to add them. However if it will only pick one marker at a time, I guess it doesn't matter.
