Why does this look the wrong colour?
Choose what the problem is with, then the symptom. Each likely cause comes with a test you can do without special equipment; mark what you find and the likely causes move to the top.
How this works
20 symptoms across 7 kinds of object, each with its likely causes, a test for each, the cheapest fix, alternatives and when to get help.
Causes start in Colourwise's order of likelihood, an editorial judgement; your answers move confirmed causes up and ruled-out ones down without hiding any.
Limitations
A self-test can mislead — especially judging colour in poor light or from memory. Compare against a reference in the same light where you can.
It covers common causes, not every one. Valuable, antique or safety-critical items belong with a professional.
Rooms and outfits have their own, more detailed diagnostic tools, linked from the relevant symptoms.
