This is fantastic.
I spend a lot of time finding the right spray paints and painting my 3D prints.
I am a professional designer so color matching is very important and a significant part of my work.
However coloring plastics is much more than just mixing R, G and B values. Can you work with the Pantone system and ascertain that it will match?
Also do you have any user reviews comparing your filaments to other brands? How much will the price be per roll, incl. shipping to the Netherlands?
