“I said your hair is a terrible red, but don’t worry. I had a friend once who had red hair like yours . When she grew up, it became a beautiful brown.”
Why is there “a” in front of “terrible red” and “beautiful brown”? Isn’t it okay to say “Your hair is terrible red”? I guess… there are so many hues or shades of each color and the speaker want to say a hue of the color. What do you think? I’m curious.
