Very cool but before clicking on some dots I was wondering why everyone feels the same. The colors are not ideal for red/green colorblind people (is it blue and purple?)

Maybe include a feature to select the colors for happy/sad/average with a button to return to defaults?

Black for sad, light grey for neutral, something like a medium bright green for happy would be my picks.

cool idea - i tried to pick perceptually separate colours and thought blue and red would work, but turns it's confusing for some people. I might add "colorblind" mode and use your colour range.

"colorblind mode" is an antipattern. Using more contrasting colors and using other distinguishing features such as shape and texture benefits all users.

How about having numbers in the circles?
