Terms
Rang is a free guide. Use it to learn, design, teach and share.
Accuracy
Colour pages are written with AI assistance from open sources and checked automatically. They can contain mistakes, and sources themselves can be out of date or one-sided. Meanings of colour are often disputed and differ from place to place.
Colour values
Values are approximations. Do not rely on them for print, paint, safety signage, brand or accessibility work without checking the relevant standard and testing on the real material. The colour-blindness views are simulations.
Not health advice
Some pigments and dyes are poisonous. Rang describes them; it does not tell you how to handle them safely. Nothing here is medical or psychological advice.
Reuse
Photos belong to their authors and are used under the licences shown beside them. Text on colour pages and country overviews is derived from Wikipedia and is available under CC BY-SA 4.0. Emotions, meanings, colour cities, the calendar, concepts and the glossary may be quoted with a link back.
