Your first tap on Love or Nope (buttons or arrow keys) starts your own brain from scratch. The net retrains after every tap, and its neurons glow as they fire. After 20 swatches you get a heat map over the color wheel (bright = it would say yes; a slider changes lightness), a 5-color palette, and guesses on new swatches so you can check whether it actually learned you.

It trains a small net on 20 Love/Nope color taps in the browser, visualizes neurons pulsing during training, and renders the learned function over the color wheel as a heat map. The trained weights fit in a share link, so two people can compare with a match score. Everything is client-side, nothing uploaded. It's aimed at people choosing colors, not at developers, but you may find the in-page training fun to poke at. Posting here in case it's a useful example of the approach reaching a non-coding audience.

Some honest caveats: it learns from only 20 taps, so it is a rough guess, not a measurement. Colors are on your screen, real paint looks different in real light, and it does not match to paint brands. Nothing is saved, so if you reload, your result is gone unless you copied the link or downloaded the PNG. Anyone with your link can see your taste map. +> +> The most useful feedback is whether the palette it picks feels like you, or feels wron ## 7-day lines
