Remember a shade, then find it among similar colors. Play ten free Color Match rounds with shorter glimpses, memory delays and visual distractions.
Remember the color shown on the board. Once it disappears, choose the matching card with your pointer, number keys or arrow keys and Enter. The original and your choice are revealed together.
Distinct choices become more similar. Longer memory gaps and intervening colors make later rounds more demanding. The original shade is always one of the choices.
Remember hue, lightness and vividness separately. For personal comparisons, use the same display and similar lighting.
Ten rounds add up to an Instinct Score of 0–1000. Round limits rise from 40 to 220 points. Instinct’s Core separately measures how accurately you predicted your rank; it waits for at least 30 other comparable attempts. These games are informal benchmarks, not a diagnostic assessment.
