Grapheme → Color Test
Do you see colors when you look at letters or numbers? This test presents each letter (A–Z) and digit (0–9) twice in random order. If your color choices are consistent across both rounds, you may have grapheme-color synesthesia.
Duration: 5–10 minutes
Pitch → Color Test
Do you see colors when you hear musical notes? This test plays 3 octaves of piano pitches (C3–B5) as sine waves twice in random order. If your color choices are consistent across both rounds, you may have chromesthesia.
Duration: 8–12 minutes
