Why "I like pink colour" is not accepted? "I like the colour pink" seems to me kinda strange.
As I was told, that may be considered wrong by many native speakers... but also okay by others. Let's add it.
"I like pink colour." Sounds odd. However, "I like a/the pink colour." might be a typical answer to a question in a dress shop where the shop assistant asks: "What colour do you like?"
