For my draw program part i'm searching a way to propose a more interesting color selection... i've this : (limited colors)


So perhaps i could use this picture and next choose the selected r,g,b colors when user touch on it.


But how to determine the selected color from this palette picture ?

Have you some ideas?

Note this is for use with a tablet.

Thanks for your help.

Special thanks to Paul Harthen for the FloodFill method : https://forum.thegamecreators.com/thread/213305

if you want the RGB values separate and don't want to use global variables it can be done like this
