> Artists don't have handy ICC profiles to guide creating a painting
There's some paint app which uses pigment spectra and a physics model for blending and layering. I don't recall now whether/how it shows you that underlying spectra and such. If students did have pigment profiles handy as a guide, how might one imagine using that to better teach color?
- jrapdx3 2y agoI'm not familiar with an app showing spectra of pigments as used in painting, etc. Some high-end printers (plotters) incorporate spectrophotometers to measure properties of colors, but that's a highly controlled use of colorants. In contrast, a painter can use a color in thick or thin layers, mixed with white, or clear medium, among other variations. And pigments can work differently in oil vs. acrylic vs. watercolor media. The spectrophotometric properties of a pigment change depending on usage so the information gleaned from measurement would probably not be that useful. OTOH some manufacturers offer visual color mixing guides that can be helpful to artists. Here's one I've used from time to time: https://goldenartistcolors.com/mixer/acrylic?tab=color-system https://goldenartistcolors.com/mixer/acrylic?tab=color-syste... This offers matching artists colors to RGB or CMYK specifications.

It looks like there's unfinished work[5] for Krita? Mixbox[6] is related, but avoids actual spectra. > mixing guide Neat. ColorMixingTools[3] is similar, with a drop2color and color2drop, and online[4] and derived apps.
