Color terms in use
Although Toki Pona places the English categories green and blue under the same umbrella, Toki Pona speakers rarely specify the difference. Color terms are almost always used in context to specify in comparison with other colors.
The lime color is better described as laso in the first instance, but when compared to a deep blue, it’s better described as jelo. The blue is easily described by laso in the second example, but it may also be described with pimeja like in the third example.
When colors modify each other, the first color is the primary one. A laso jelo is a yellowish green which is closer to laso, and a jelo laso is a greenish yellow which is closer to jelo.
