Just to check, my understanding that 'forwards' and 'backwards' are hooked up to change a seed value used for a random calculation of the fill/stroke colour choices (an almost infinitely large carousel of random choices, left or right). Where the buttons act something like the below image to maintain the current behaviour where clicking the large Xo icon still progresses forward:

Ahhhh... Hmmm. Now, for me I think that implementation would be rather an unexpected/confusing behaviour, click the large XO and the little ones would seem to randomly change as well. Now I understand why the videos you posted caused me some confusion (I was expecting 3 colour choices in the xo < XO > xo to always scroll left or right). Do you have a clone somewhere on git.sugarlabs.org I can look at?
As per previous button mockup image, marching through a random set, left or right, would seem to provide the existing behaviour, plus the equivalent of an undo, and a mini-me preview for what would be next/before undo.
Sorry for the confusion.

But only fine tune in 1 dimension? Would have to scroll a long way to see a change in the other fill/stroke colour.

OK, sorry missed that. FWIW, I think my main objection was that for the control panel positioning case, the XO was no longer central, being off centre to the right. I guess this could be easily fixed by moving the xo < XO > xo widgets down below the grey text "Click to change your color:" so the text does no longer pushes the widgets off to the right.
