2 colors appear on both best and worst. Each lists a maximum of 5 colors. That should be enough to stop the experiment right there, unless your goal is to find the most controversial colors.

The takeaway seems to be that color preferences are highly subjective to the point that you might just be getting noise.

Also how is it that people are even seeing the same colors for this to have happened? Even with birthday problem seems unlikely that two of the exact same hex colors would end up on the two very short lists. Are you sure you're shuffling these?
