Maybe your English-English dictionary works like that, but I used my English-Finnish dictionary and because of the limited number of pages and the difference between Finnish and English it couldn't tell me more specifically the meanings. My dictionary told that tint means 'sävy', but in Finnish you can describe your feelings using this word. It also told that tinge means 'vivahde' - so it made a difference but it didn't help, because we use these words in different situations.
