TMZ Hip Hop got the Chicago rapper Tuesday outside Dash Radio, and he shared his insight on the subject -- as it turns out, his new song tackles the very same topic!!!

On "Blue Eyes," Vic lyrically details the internal struggle he had as a kid yearning to be a lighter complexion ... even admitting he yearned to be white, at one point.

Vic doesn't know Pinkydoll, but says he knows her scenario all too well, telling us the dark vs. light skin debate precedes everyone's lifetime ... and Pinkydoll was programmed to follow European beauty standards since birth, whether she's aware of it or not.

Pinkydoll's explanations for her skin color looking so different on TikToK vs. real life have been an all over the place. She blamed it on being in and out of the sun when we spoke to her at LAX -- but on Wednesday's "TMZ Live," she said it was lighting and a filter to make her "look more Japanese."

Vic says he won't cast judgment on Pinkydoll or anyone like her, but thinks it's best for everyone's mental health to learn to love themselves as they are.
