Knowing the hex code is one thing — reproducing the exact shade from memory is another. That is the whole idea behind ToonTones, a free color memory game built around pop-culture shades like SpongeBob yellow. You study a color for a few seconds, it hides, and you rebuild it with hue, saturation, and lightness sliders. Each round is scored 0–10 so you can see how close your color memory really is.
Most people are confident they "know" SpongeBob yellow until the swatch disappears and they have to set the sliders blind. Try it and see how you score. If you want the precision-focused version, the color accuracy test grades reproduction, while the color memory test stresses recall.
