What color should the name Kaoru or Mihoshi should be?

It would depend on the kanji utilised. The latter could be either Ocean Star, Bright Star, Beautiful Star, Future Star, et cetera. One of the given characters for Kaoru can be Summer. Although the world of Remnant is not Japan, you can decide which of the many character combinations that could be read as those names would give a colour you find workable.
