How to Play

Both games share the same three-step loop. Differences are noted below.

1. Step 1

   Memorize

   A target appears for a few seconds. For Color it is a solid swatch (5s Easy / 2s Hard). For Sound it is a single tone (2.5s Easy / 1.25s Hard).

2. Step 2

   Recreate

   For Color, drag three sliders (Hue, Saturation, Brightness) until the swatch behind them matches what you remember. For Sound, drag the frequency slider until the tone you preview matches.

3. Step 3

   Score

   A perceptual distance is computed — ΔE2000 for color, cents for pitch — and graded out of 10 per round. Five rounds → 50 max.
