I have now added real photos to the site for most filaments, some still look a bit off such as the dark grey and muted colours but please use these photos as guides, the renders are honestly way more accurate for most filaments. I did spend a bunch of time trying to make the colours as good as possible but I still fked up.
So please use a combination of the renders, listed hex codes, and photos of the filament to make the most informed decision.

You could put so much effort into getting the colours to look right and someone may still have weird contrast or hue settings on their monitor that make it look completely different.
Ah man.. Real world vs screen colours are always a pain. If one day you could put similar colours together in single photos, that would be an even greater reference point. Any kind of real photo is still appreciated, thanks.
