> The effects of redlining, as noted in HOLC maps, endures to the present time. A study released in 2018 found that 74 percent of neighborhoods that HOLC graded as high-risk or "hazardous" are low-to-moderate income neighborhoods today, while 64 percent of the neighborhoods graded "hazardous" are minority neighborhoods today. “It’s as if some of these places have been trapped in the past, locking neighborhoods into concentrated poverty,” said Jason Richardson, director of research at the NCRC, a consumer advocacy group.
The linked page[0] goes into more detail about how disastrous this was and the impact on wealth it has to this day. Considering how neighborhoods were even less integrated then than they are now, it's safe to say the correlation of redlining to skin color was very high.
