Haven't seen a template for any CMS with color sorting?

Question

CMS

Hello! Tell me, maybe someone somewhere met a ready-made solution for any CMS with sorting not only by tags and headings, but by color? Something like this - landingfolio.com or this - slidesgo.com ? I understand that "you can finish it there, a regular template, etc." I also know that this is possible, but this is an extreme case. Maybe someone has already seen something like this already finished? Paid or free - secondary, the price is also secondary. Thank you!
