TWIL #010 - Your Language Shapes What Colours You Can See
Some languages have words for colour distinctions that others don't - and speakers of those languages genuinely perceive the difference more sharply.

The Pirahã tribe in the Amazon and the Himba people in Namibia can distinguish shades of green that most English speakers cannot easily tell apart; not because their eyes are different, but because their languages have distinct names for those shades.
This is called categorical perception. Having a word for a colour category creates a sharper perceptual boundary in your brain. You literally notice the difference more readily because your language has given you a hook to hang it on.
A famous historical case: ancient texts almost never mention the colour blue. Homer's Iliad describes the sea as "wine-dark." The sky is never called blue in ancient Greek, Sanskrit, Chinese, or Hebrew texts. Some researchers believe ancient peoples didn't distinguish blue as a separate category - not because they couldn't see it physically, but because they had no word forcing them to pay attention to it.
The effect is strongest at the boundary between two named categories. English speakers are quicker to distinguish "green" from "blue" than two shades that both fall within "green" - because crossing that linguistic boundary triggers faster recognition.
This sits in a long-running debate in linguistics: the Sapir-Whorf hypothesis, which argues language shapes thought. The colour perception evidence is some of the cleanest empirical data supporting a weak version of that claim - not that language limits what you can think, but that it influences what you readily perceive.
