Question 1

What is Shade Finder?

Accepted Answer

Shade Finder is a free color vision test and game. A grid of colored tiles appears on screen — one tile is a slightly different shade. Find it before the timer runs out. Each level adds more tiles and brings the shades closer together, making it progressively harder.

Question 2

How is my Color IQ calculated?

Accepted Answer

Your Color IQ score is based on the level you reach and the minimum color difference (ΔE) you successfully detected. ΔE (Delta-E) is the standard scientific measure of color difference — a lower ΔE means you can distinguish much subtler shades, indicating sharper color perception.

Question 3

What is the Daily Challenge?

Accepted Answer

Every day a new seed color is generated from a curated palette. In Daily Challenge mode everyone around the world plays with the exact same color sequence, so you can compare scores fairly with friends and other players.

Question 4

Can Shade Finder detect color blindness?

Accepted Answer

Shade Finder is a fun perception game, not a medical diagnostic tool. However, people with certain types of color vision deficiency may find the later levels particularly difficult. If you suspect color blindness, consult an eye-care professional for a proper Ishihara or Farnsworth-Munsell test.

Question 5

Does Shade Finder require sign-up or installation?

Accepted Answer

No. Shade Finder runs entirely in your browser with no account, download, or installation required. Just visit the page and start playing.
