A while ago, I needed some backgrounds for screenshots of the pajama recolors I made(which will also be available here soon), so I made a beige and a light blue one. Once I did that, I thought, might as well upload them, and made a rainbow of recolors for uploading. The pajama recolors will take a bit to upload here because I currently can't properly reflect their requirements, but in the meantime, have a rainbow of marbled CAS backgrounds(this is the purple one, the others will be linked)^^
The hair shown in the screenshots is from Obscurus Sims. The shoes are EA/Maxis.
