Cosmetic legacy gardening pots

In light of the future nullification of our (in some cases) wonderful gardening pots, I'd like to propose you make the old ones acquire some sort of cosmetic change based on their old elemental composition. For example my best sulphur pot could retain its old elemental composition in the form of color components, making the pot be closer to the color of its main element with increasing purity
Not a really important thing, but it'd be fun for those of us attached to our precious pots. Want the good ones to stand out a bit, for nostalgia's sake
