Hello Astoria57 and welcome to the ArtRage forums

Now I must confess, I don’t actually have any of the mobile versions of AR, just the desktop versions.
So this here is all just my best guess!
But it looks to me like you somehow managed to changed the picker to what would be on the desktop version, RG / B picker mode.
If you tap and hold on the colour pod, do you get an option to choose another picker mode i.e. LS / H mode?
Or, if you go into the apps Preferences can you reset it there to LS / H?
