I'm not a vocalist or have any experience in singing. This is just my opinion on their color/style/tone whatever.
Not in any order
Shijak
Irene: Irene's singing voice's strongest points, to me, are its soothingness and calmness, but this is overshadowed by monotony and breathiness, which also makes her voice seem "tight". Anyway I like her rap voice.
Yeri: High voices are generally not my thing and this applies here as well but thankfully rvs dual concept makes me see that her voice goes pretty well with their Red songs. Like Irene, I prefer her speaking parts in their songs more.
Joy: Her voice is like honey, it's sweet, it's high but also full. Good for Red. Hello fit her voice like a glove.
Wendy: Recognized by everyone, me included, as one of the best main vocalists, but I've never paid much attention to her vocal color until Like Water. I think her voice definitely suits songs like that more. Her voice sounds like it has a lot of force and the quick tempo of their more fast poppy songs sometimes don't really do justice to that, but luckily there's always her high notes.
Seulgi: I love deeper voices, so I love hers too. It suits their RnB songs really well. I remember I read somewhere that her voice was "nasally" though. Is it?
