How do you say "mellow" in japanese?

Question

Looking for translation of "mellow" in japanese. Or any synonym of "mellow". ie. relaxed, chilled, easy-going etc...

Answer 1

I thought you were asking the colour Mellow in Japanese.

Anyway, since you're asking about human personality. I guess

楽ちんな人（Rakuchin na hito)＝Easy going person/Pleasant person

Rakuchin（楽ちん）＝Pleasant, Easy going

な（Na)＝Rakuchin is a Na Keiyoushi word.

Hito=Person/Human

Answer 2

enjukushita (as in 'her personality has become mellow')

nonki (as in 'he's easygoing')

mutonchaku (as in 'he is quite indifferent to her suffering')
