Kim Kardashian is Pretty in Pink Amid Kanye West Drama

Kim Kardashian's simply opting to go pretty in pink as the ugliness with Kanye West rages on, OR it's all so stomach-churning ... she's got Pepto on the brain.

Kim dressed head-to-toe in Balenciaga while running errands Monday around L.A. with North and Penelope Disick -- who both followed her lead with pink and red outfits, respectively. Musta been a Valentine's day thing.

Check out the gallery ... Kim was popping with her bright pink jacket, and matching sweater and matching thigh-high boots.

We're gonna go out on a limb and say she's firmly in the pink!

Her family time comes on the heels of Kim's romantic weekend in NYC with boyfriend Pete Davidson ... as we told you, the couple got a jump on the holiday with a date night sealed with a kiss.

Kanye, meanwhile, has been ranting and spreading nasty rumors about Pete on social media ... but it sounds like he's finally changing his tune.

Ye just posted a sort-of-apology for posting Kim's text messages ... and said he's working on his communication, moving away from ALL CAPS and taking accountability, saying ... "Sharing screen shots was jarring and came off as harassing Kim."
