So i don't want to fully sleeve my psu cables yet so is there any way to just get rid of the rainbow of colors at the end?
What do you mean? You could but extensions, presleeved.
I am willing to sell my sleeving services, as well. MDPC-X and para, full cables and extensions.
bit fenix extensions are the first thing that springs to mind. You'll still have the standard cables coming out of the PSU but the other ends of the cables will all look sleeved.
if you push sleeving braid together it gets bigger, just slide it over the cables and don't use heatshrink

Well I didn't really want to with extensions. I was thinking something cheap like electrical tape but that wouldn't work.
