I came across this sentence:
「あんた ホントに どどめ色の青春を過ごしてるわね」
The context is that the addressee wanted to show the speaker a new move he learned by watching the same video over and over again.
Apparently 「どどめ色」 refers to a certain color (https://www.weblio.jp/content/%E3%81%A9%E3%81%A9%E3%82%81). I cannot really make sense of what it is supposed to mean here though. Are there any other examples of a color modifying 「青春」or are there any set phrases that help understanding the construction here?
