After choosing the foreground and background color of your orb, you click on "Update" and see the chosen orb - which is a preview anyway.
No offense, I don't get why there should be another button to do the exact same thing as stated above. It wouldn't even save time or clicks though.

Additionally there is already a post designer from 2011 covering this idea:

I've thought this many times. No idea why it's just now getting recommended. I used to have 8 sigs/avas that I kept in rotation and would change the weekly and sometimes twice a week. Luckily after changing them so often I just wrote down the color codes but this would have been a nice feature.
Got my yes.
