Jinni's beauty is no joke. She is not just an idol. She comforts everyone with her voice. Even a smile of hers lights up my life.

Bae's voice is just so versatile. She can rap AND sing such a beautiful tone at the same time. She definitely owns this song, because it suits her so well.

This song is criminally underrated.

Yall talk about their voices, imma talk about the production of this song. It sounds so amazing, especially that low bass 808 in the background. Its sounds so nice and adds flavor to this song. Amazing.

I'm a big fan of Lily but all the other members are so talented too. This group is so underrated, their vocals are on another level

Jiwoo's style, vocals, rap and visual WOW AMAZING!!! ❤️🔥🔥😘😘😘😘 NMIXX

Bruh, Jiwoo's rapping part in this song is so good! Not a swaggy rap but more light and bouncy. Such a vibe when her part comes.

난 아무래도 이게 내 최애곡임 몽글몽글하면서 배이의 도입부부터 끝에 가사와 목소리가 너무 잘 어우러짐 뮤비분위기는 둘째치고 편집이나 엔깅이들 얼굴이 받쳐줘서 너무 너무 맘에 들어요!!

Jiwoo is not even my bias, but I am so mesmerised by her beauty, her voice is such a candy to ears 💓

NEED THIS CONCEPT FOR NEXT COMEBACK! ANYONE AGREE???

Baes voice in this is heavenly. One of my fav NMIXX songs

엔믹스 최애곡중 하나 들을때마다 힐링받는거같기도 하고 홀리는거같기도 하고..

Bae’s Voice is sooooooo good to start this song. Her voice is definitely underutilized in this group. She definitely needs to be featured more.

The deeper I get into NMIXX, the more I love Jiwoo. this girl holds too much talent.

wow this song is a hidden treasure unlike anything i've heard in kpop so far

역주행 가자 쯈 너무 좋다구

This is Bae's era. The visuals. The vocals. She owned this song.

MVマジで可愛いしイントロの音楽のちょっとしたクラッシック感も最高に可愛いし最初のお部屋も雰囲気あって超可愛いまじやばいなしかもMVだからこのビジュアルなのかMVでもこのビジュアルなのかはわからないけど顔面が全員強い。本当に可愛い

kpop 중 가장 좋아하는 노래

This is their best song in my opinion. The fact that every one of them is a talented singer with no vocal holes is fantastic. NMIXX is one of the best vocal groups in Gen 4.

bae literally owns this song. her tone is like a breath of fresh air, it’s so nice. this whole song is so good! gonna be on repeat for days 🤭

this is completely off topic but the main reason i love this song is because my childhood teddy bear is in the mv 😭 it’s a great song i love it don’t get me wrong but that just added onto it being one of my favorites!

이 노래 정말 좋음 ㅠㅠ 멤버들 음색이 잘 드러나기도 하고 깔린 반주도 너무 마음에 듦

Bae’s intro is magnificent, didn’t realize she owns such a pretty voice until this song, i rlly want to hear her more in Nmixx songs, anyway she shined in this one

I’m obsessed with this song

This is a masterpiece and these are arguably the best vocals of 4th gen. More songs like this for them please JYP. 😭

도입부 배이 진짜 미치겠음 얘 왜케 잘하냐

엔믹스 이번 수록곡 진짜 미쳤어 너무 좋아..ㅜㅜ 첫 시작이 배이 인게 신의 한수

I didn't expect a song like this from Nmixx, and I love it so much, I can't stop listening to it, they are so good vocally, I'm proud

Nmixx are so underrated, they deserve more and more recognition

쿨 역주행 하면 좋겠다 노래 진짜 좋은데...

Their voices are so mature, it doesnt seem like its coming from such young people

Every member has such beautiful voices, JYP should record 7 versions so we get to hear a full song of "cool" sang by each member! 😍

この歌はベイが主人公な感じする ジニがいなくなってからエンミ知ったけどいないの悲しすぎる

I'm so happy Bae is getting the attention and lines she deserves. She is definitely one of the most underrated members of Nmixx and I'm glad that she's getting the lines, screen time, and attention she deserves

Jyp really said " vocals "😌 Would love to see the members harmonize and sing live once

this song's vibe is just- something else and I love it

Jinni's visuals wow. This kind of concept really fits nmixx so much. We definitely need more of this ballad-kind of song and concept!! Mixxpop + Ballad is a perfect combo!!

This song is so melancholic, it's like a memory I never had and at the same time like a breath of fresh air and a pat of encouragement on the back. Definitely my favourite.

진짜 몽환적이고 좋다.. 이 영상에 나오는 야외씬? 거기 날씨가 노래랑 진짜 잘어울림... 맑은데 구름많은 날씨가 쿨이랑 찰떡

I dont stan them but this is definitely in my current top kpop songs of all time, every literal second is perfect, vocally and musically such a beautiful song, i wish kpop had more of this kind of sound

JYP This how you release the full potentials of your vocalist. This is a masterpiece of NMIXX. They should have debuted with this.

Honestly I like to see JYPE give them more songs like this, this song was PERFECT

5 months passed already and yet this vid has 4.4M only!?, it deserve to be 10M by now🙃 #SLAYMIXX

as a child i was thinking about a dreamy song full of pure innocence that makes me forget all of the dirt that got on me over the years. i finally found it.

쿨 처음에 듣자마자 너무 좋아서 이것만 무한재생 중 ㅋㅋㅋ 타이틀 곡 다이스도 다이스만의 매력이 있는데 이 쿨은 진짜 한 번 빠지면 절대 빠져 나올 수 없는 매력이 일품인듯

As I watch this video, it just proves how JYP never disappoints us with their girl groups. NMIXX is a masterpiece 💕 Love 'em all

모든 멤버의 음색들이 너무나 좋다. 알면 알수록 엔믹스는 최고인듯

エモすぎる、、。COOL好きなんよ❤

곡이 엄청 몽환적이면서 좋은데 또 멤버들 음색이 너무 잘 드러나는 레전드 수록곡..

1:18 Jiwoo’s low, husky voice is seriously addictive.

this is easily their best song

be honest...nmixx doesn't have bad song

갠적으로 이 노래 너무 맘에 듦.. 진짜 멤버들 음색 다 살린 노래

Bae's voice is perfect for this song

This song is so underrated

This is the only NMIXX song that I truly enjoy and the only NMIXX song that's really listenable.. their best song ever

All these girls are amazing simply amazing. Jiwoo has a lovely tone, Kyujin is always good, Lily is a super nova, simply insane. Than Haewon lovely as ever. Sullyoon, just so refreshing and sweet, and than Jinni, her sing/rapping tone is just so creamy and enriching. Than Bae, my Bae lol, her tone is just honestly out of this world, so deep and raspy, her versatility and shifts are way beyond her years, like a full grown woman doing this for ages.

this is bae and jiwoo's song, idk why but they just suit the whole song's vibe and style sm! hoping for more songs like these in the future as well :3 also I have to say that lily has such a beautiful voice as well

Jiwoo es tan linda y carismática, me encanta que con cada comeback tenga un poco más de atención por parte del público. Espero que en el futuro ella pueda brillar aún más y todo el grupo en general porque se lo merecen.

It's been a year (gonna be 2 years in late September) and I still love this song. This song never gets old to me & still sounds fresh. So refreshing & amazing. My ultimate favorite song.

I’m so glad they released a mv for this song!

Jiwoo and bae both are talented and visuals

เพลงนี้ดีเสมอ❤

정말 아름다운곡이야❤

NMIXX's vocal colour are no joke, starts with Bae and ends with Sullyoon. I'm in love with this masterpiece and it could be an OST

This is one of the only groups i genuinely like and am interested in because of how entertaining they are, the bad news about jinni leaving breaks my heart 😕

このジウ好きなんよねビジュアルもラップも

쿨~ 노래 좋네요.

They should have debuted with this song

jinni is genuinely one of the most talented idols i’ve ever seen, she trained for so long and gave up her whole childhood to become an idol, my heart goes out to her and nmixx, losing a member barely a year into the groups debut must be terrifying

The track ‘COOL (Your Rainbow)’ is a song that talks about the fact that the negative emotions that we often consider ‘not cool’ or ‘toxic’ is also a precious part of our mind. It compares the process of us recognizing and gathering all of the emotions that we feel in our daily lives to the changes in the weather. This song is about the journey of NMIXX, who will explore through their emotions, emitting their newfound light as they find their new rainbow while walking through their days of fogs and darkness. ‘COOL (Your Rainbow)’ is a pop ballad track that combines the 808 bass & trap beat along with a variety of sounds of dreamy brass and classical strings. The unique tone and special talent of NMIXX will be highlighted through this track.

숨어 있는 명곡.... 👏👏👏

i hope jyp doesnt do their jyp thing where when someone has a deep voice they're either turned into rappers or forced to sing in high pitch. bae's vocals are so insane i hope jyp takes care of her well her voice is insanely unique

BAE AND Jiwoo really impressed me in this one, Jinni,Haewon and Lily keep on eating. Sullyoon and Kyujin just are soo angelic😭😭🔥🔥🔥

JIWOO IS SO BEAUTIFUL AND TALENTED💖

1:34 可愛い 0:42 たぶんわたしが推すならこの子なのかな

이 노래 진짜 개인적으로 최애곡.. 노래 너무 좋아ㅠ

Bae's stylistic voice really fit the beginning. 😍 The girls slayed this song so hard

Nmixx is definitely a group full of visuals, they are all so beautiful!!!

もっと知られて欲しい名曲

작곡도 작곡이고 가사가 진짜 힐링...힘들 때 찾아 들음

7명 멤버들 다 각자 목소리 포인트를 잘 보여주는 최고 수준의 수록곡이 아닐까 싶습니다 도입부 베이부터 시작하는 것 정말 신의한수 음색 너무 독특하다~

jiwoo's visuals are no joke

ชอบมากกเพลงนี้ควรแมสสุด🥺

why's this song not viral😭😭

My jaw dropped when Bae opened the song. It was so good!!!

0:13 bae was so cute while singing her part and also her voice really gives me goosebumps. I hope she will be recognize more soon because her voice was so lovely. Anyway stan NMIXX you won't be regret!

awesome🥲❤︎ 全員美形、歌もdanceも上手いって化け物groupなのよね本当😭🦋💘🫧jinni❦

this song is underrated.

"A rainbow isn't a rainbow anymore without seven colours..." Anyways, Jinni we will support you! Stay healthy and happy! 🤍 Edit: Thanks for all the likes, I hope Jinni can see this and be happy 😺🤍

Finally, a normal-sounding song that utilizes their beautiful vocals!!! I really want to see more of this!!

This song is so good and very fits each members' voice

엔믹스의 성공에 나의 목숨을 겁니다

uhhh this is too damn good? I didn't know Nmixx has so many strong vocalists! Definitely don't mind them going into more soft territories like this one. This song actually made me more interested to get to know the band and their members

이 곡 완전 몽환적이고 신비롭고 다들 노래 음색 넘 좋음

めっちゃいい曲だな。何で伸びてないんだろ

1:18 최애파트..짱좋아요 진심 ㅠㅠ

아니…7명 빠짐없이 이렇게 예쁠 수가 있는거야…? 뮤비 감성도 너무 내 스타일이라 놀랐네🫢

Their’s vocals are no joke! So talented! It’s NMIXX
