We have a much more abstract concept of color today than people had in the pre modern area.

Before the days of color charts, the colors and textures of objects were often described by analogy to other objects.

And the color descriptive analogies didn't have to be consistent across all their uses. They just had to work in the context in which they appeared.

Kind of like orange, rose, pink... though I doubt most people consider the literal meaning when using those adjectives (except for rose perhaps).
