Translation:This color is pretty.
Again: kirei is pretty. Utsukushii is beautiful. Japanese put a lot of effort into using the right words at the right time, so it is unwise from Duo to mix things up like that... (see: kirai vs. suki janai case - there is a difference between hating and not liking something).
The audio is still wrong but have to check update , sounds like the colour is harakiri :-D
