Blender allows for creating procedural materials with more and more precision using nodes.
YInMn Blue, the pigment discovered in 2009 at Oregon State University, has finally been approved by the EPA for use in artists' materials.

YInMn Blue (/jɪnmɪn/; for the chemical symbols Y for yttrium, In for indium, and Mn for manganese), also known as Oregon Blue or Mas Blue, is an inorganic blue pigment that was discovered by Mas Subramanian and his (then) graduate student, Andrew Smith, at Oregon State University in 2009. The pigment is noteworthy for its vibrant, near-perfect blue color and unusually high NIR reflectance. The chemical compound has a unique crystal structure in which trivalent manganese ions in the trigo The di...

If access is given to the material’s spectral response we should be able to accurately model it with Cycles spectral build ! but I don’t see it anywhere, I reckon it must be protected by a patent.

Here is a paper from smilebags on devtalk about Cycles and spectral rendering.
Feature & Design Feedback
Hi, I’ve created a workflow with which users can render spectral images with Cycles. At this stage, I’m not proposing to turn Cycles into a spectral render, but have been encouraged to bring it up here as a point of discussion. I am aware Cycles...

I did retrieve also a post on BA about a build for Cycles spectral rendering engine.
ONE MORE UPDATE: There is now a graphicall daily build available for Windows which will contain my latest progress in converting Cycles into a spectral engine.

ANOTHER UPDATE:
Over on this devtalk topic I’ve been working on modifying Cycles to be a spectral renderer from the ground up. Progress is slow since I’m unfamiliar with the Cycles code but it seems achievable.
UPDATE:
Since the start of this thread, significant progress and changes of t…
Yes that’s the one I was talking about. They’ve been making tremendous progress. Have you had any luck finding actual data about this new blue pigment ?
No at this time because I am swamped on a project, but I will contact some people that are in that field…

It’s Hex Code is #2E5090 sRGB B (r , g , b ) (45.82, 79.92, 143.51)
Great! Thanks for that info… It was really nice.
