Arrange color caps like the clinical Farnsworth D-15 test to build your personal correction profile.
Find your color vision profile
This test is modeled on the Farnsworth D-15, the color arrangement test eye doctors use. You place 15 color caps into a smooth run, starting from a fixed reference cap. To someone with a color vision deficiency, two caps from opposite sides of the circle can look alike, so they end up side by side. Those crossings show both the type of deficiency and how strong it is, covering the full deficiencies, the milder anomalous forms (protanomaly, deuteranomaly, tritanomaly) and complete color blindness (achromatopsia). The result becomes the profile the image and camera tools use to shift colors for you, and a pair of links to hand someone your own view.
Use normal screen settings (no night shift) in comfortable lighting. The colors are approximations shown on your own display, so this is a self-check, not a diagnosis.
