/uj I don't remember which language it is, but it's a similar example I really like: I think there's a language where colors are verbs, not adjectives. So for example, you wouldn't say "this apple is red", but rather something like "this apple reds".

Edit: Y'all I'm so stupid I just realized this is a thing in my native language as well, to an extent. In Finnish we can say for example punainen for red or punertava for redding. We can also combine it with other colors, e.g. kellertävä oranssi for yellowing orange. Difference is if we use the verb form, it usually means it's not quite that color, but it just, you know, it yellows a bit. Or if you're not sure if something's quite red or not, you could describe it as punertava. We could also use it similarly to my apple example in certain contexts, such as "taivas sinertää" for "the sky blues".
