Frequently Asked Questions
How does this work?
Browser displays calibrated test patterns. You judge banding, gamma, color uniformity by eye. Not a colorimeter substitute, but catches obvious display issues.
What is gamma?
Brightness curve mapping signal to luminance. sRGB standard ≈ 2.2. Wrong gamma = washed-out shadows or crushed highlights. Test pattern: alternating black/white squares should match the gray.
When do I need a colorimeter?
Pro photo/video work, print prep. Tools like X-Rite/Datacolor cost $200+ but measure absolute color. This browser tool is for sniff-test, not production accuracy.
