Perhaps for some developers in the Middle East with iconic projects and massive budgets. You would want to know how long the functionality lasts, and whether this pigment loading compromises the coating in other ways. Epoxies in general are not very green, typically made with bisphenol-A, it would be interesting to see the EPD for these products.
In my opinion natural materials that don’t need coatings are a better option… still, extending service life of assets has advantages in reducing future embodied carbon.
