Every tool is visible at every tier; above-tier calls return a structured requires_tier error with an upgrade link rather than a bare failure.

Notes on the data

Colour data is factual information gathered from public manufacturer sources. Hex values are sRGB approximations of physical paint — always check a sample pot before committing. Prices are indicative and change; coverage figures are the manufacturers' own. Trend data is a relative 0–100 interest index derived from site engagement, not industry sales.

All Paint Colours is not affiliated with or endorsed by any paint manufacturer; brand names identify their products.

Licence
