Apologies if I just missed this, but is there a link to Maxwell’s original findings?
Maxwell's "color wheel" experiment (https://cudl.lib.cam.ac.uk/view/PH-CAVENDISH-P-02000/1) is more commonly known, which preceded this experiment I wrote about. (Which by the way is also a very clever experiment which blends color by spinning a wheel with different ratios of primary colors).
Here's a link to Maxwell's original paper: https://royalsocietypublishing.org/doi/10.1098/rstl.1860.000...
You can see some diagrams of his original apparatus that I worked off of in the last two pages!
What are you developing a spectral CMS for? Is it for lighting or materials or something imaging related?
The CMS I'm building is for creative imaging—I want to model some specific subtractive processes from the physical world digitally. In the process, I had to come up with a way to convert RGB to spectral power, and was surprised to find that while there's a Spectral -> XYZ function (CMF), there's no industry standard inverse (XYZ -> Spectral). So I came up with a function which allows you to specify three RGB peaks, along with their widths, and it solves for the correct peak levels to reproduce an XYZ equivalent to the input color. This is my idea of fun! haha
