Ah, classic. Exactly what I was hoping to see :')
Totally mischievous. I absolutely hated selecting my desired color. It took so much time. I lost count countless times and had to scroll back up each time to check where I'm at.
On top of that, checkboxes are TINY, so it's not super easy to quickly click through all of them. And I get pissed that much more if I miss one and fall out of my "rythm".
A simple design which managed to be overly impractical, which is something I truly appreciate. Great job, you nailed this challenge!
