Small tests, honest science.
tintfall is a small collection of tests built on one rule: the fun can be silly, but the science underneath can't be fake. Every test on this site tells you exactly what it's based on, links the actual research, and is upfront about what a three-minute quiz can and cannot know about you.
Why we made this
The internet is full of personality quizzes that invent their results, and "vision tests" that hand out percentiles from thin air. We thought the fun didn't need the lying. A personality test can be a pretty color and run on the Big Five. A color game can be addictive and admit that your screen affects the score. Being honest turned out to be a feature, not a limitation.
Three promises
- Your answers never leave your device. Scoring happens in your browser; share links carry only final scores.
- Every test links its references. If we can't cite it, we don't claim it.
- Estimates are labeled as estimates. No fake precision.
Made by
tintfall is made by a motion designer in Seoul who spent years making things look good and now wants tests that are good. Design, code, and stubborn honesty included.
