What is the meaning of やさしい色のソフトカラー


I recently bought some highlighters from Japan that are pastel in color and on
the front it says 「やさしい色のソフトカラー」 and I'm a bit confused since 「やさしい色」and
「ソフトカラー」both, in my mind, mean "pastels" so I don't understand what the の
connecting the two means since they're both the same concepts.

What would be a good translation?




This sounds like an unnatural tautology to me, too. Sometimes people use two
similar words effectively to emphasize some concept, but in my opinion, this
tautology is not working very well as a catchphrase. You don't have to worry
about this too much.
