The Grammar of Colors in German
could someone post a guide of all the basic colors, (colors of the rainbow and brown, pink, black, white etc...) and when their grammar changes due to the sentence they are put in? I'm having trouble distinguishing.
The ending changes like for any adjective
Well, not all of the colours -- there are some such as rosa, lila, orange that don't take endings, at least not in the standard language.
Then you have to say either das lila Auto or das lilafarbene Auto, but you can't say das lilae Auto. (Though informally, you may hear das lilane Auto or das lilale Auto.)
