How can I paint this picture when the color blind is hanging with you
Metaphorically, to paint a picture is to describe something clearly. It is difficult for Kendrick to describe the pain he’s been through to someone who can’t see colors. This alludes to thinking in terms of black and white, which is to lack a nuanced perspectives on complicated topics
In Kendrick’s life one might say red and blue instead of black and white — colors are extremely important in the gang culture that had such a strong influence on Kendrick’s early life and this album. Gangs operate somewhat like cults, and members may be blinded by their gang indoctrination
By hanging with the color blind, Kendrick may be referring to hanging out with bitches (dogs are color blind), in this case women (or weak men). They may be killing your vibe and not allowing you to see things as they are.
Blind is also a play on words, since hanging a blind suggests pulling down a blind on a window, in this case perhaps the listener who is unable to see through the window into Kendrick’s soul. Following this line of wordplay, there might also be a pain/pane thing going on.
He’s also saying that the picture he’s trying to paint is one that includes a type of pain that many don’t understand and can’t empathize with (hence the previous line You don’t know what pain is)
