In Japanese, the words for colors can be divided into two groups. All colors are nouns in their base form, but some can be turned into い-adjectives by attaching an い at the end, and some can not. Below are some sentences containing color words that are い-adjectives.
We can place these in front of nouns just as we can with any other い-adjective.
The color words below cannot be turned into い-adjectives however. We can make them adjectival by using the particle の, just as we can with other nouns.
