Not Every Language Has a Word for Blue
Ask a child to point at something blue. It takes about a second. Now ask every language on earth to name that same colour, and the answers stop agreeing.
Where the Colours Divide
Languages do not cut the spectrum in the same places. Several use a single word that stretches from leaf green all the way to sky blue, and speakers of those languages see no gap there at all. Others are precise where English never bothers, with separate words for the colour of a particular soil, a particular cloth, or the coat of a particular animal.
No system here is missing anything. Each one names what its speakers needed to name.

Colour Words Carry a Whole Culture
Many colour words are really the names of things. A dye plant. River mud. Ash. Ripe fruit. The hide of a favourite cow. Learn the word and you often learn what grew nearby, what people wore, and what they traded.
This is also why colour vocabulary is one of the first things to thin out when a language stops being spoken at home. The fine distinctions go first, because nobody needs them at the shops.
Try This at Home
- Learn the colour words in your family language before almost anything else. The world is already full of practice material.
- Ask an older relative what a colour is named after. The answer is often a plant, a stone or a cloth.
- Play a slow version of I spy on the walk home, one colour each time.
- Sort the laundry or the fruit bowl out loud in the language you are learning.
- Let your child correct your pronunciation. Children are ruthless, and it works.

The Light You Grew Up Inside
Your first language handed you a set of lines drawn across the light, and you have been using them ever since without noticing. Learning another language moves those lines. It is a small, strange, permanent gift, and children take it in without blinking.
