> Toki Pona has a five-color palette: loje (red), laso (blue), jelo (yellow), pimeja (black), and walo (white). Like a painter, the speaker can combine them to achieve any hue on the spectrum. Loje walo for pink. Laso jelo for green.
So, what's Toki Pona for cyan, which two colours would you combine to create that colour? (Blue = cyan + magenta)
Or how would you describe 'magenta' in Toki Pona? (Red = magenta + cyan)
See the problem with using Red, Yellow, Blue + Black, White is that Red and Blue are pre-mixed! You're cutting out two of the true primary colours (magenta, cyan) which means you're significantly reducing the amount of colours you can accurately describe.
On the other hand, still using just five words: Cyan, Magenta, Yellow, Black, and White CAN describe nearly all of the colours we would need to communicate with language.
I wonder if the rest of the language is as well thought out as the colours...
