As a traditional and digital painter, there is one unique feature that is easy to overlook: the colors are selectable as true pigments.
Painters don't categorize colors using standard terms: red, blue, green etc. Rather they categorize according to pigment. Different pigments (i.e. chemical base to the paint) have different properties.
For example, a Prussian blue appears almost black when applied thickly, but is very chromatic when applied thinly. In contrast, a cobalt blue is pretty much the same however it is applied.
ASAIK, this is the only app that supports this feature out the box.
The digital painting toolset has been pretty much in stasis for years, but this app offers node based brushes! I am very intrigued. Downloading it now.

Is that allowed under GPL V3 to limit commercial use?
The project is a mix of licenses since it's a mix of components. If I had to guess, they intend source code and maybe the binaries under GPLv3 that they own, fonts under SIL Open Font, but "brushes" and "splash images" under CC_BY_NC, etc. mean they could probably constrain certain uses:

My personal opinion is that if that's what they intended, it seems quite reasonable.
For a featureless program it appears to be quite featurefull !
Opaque and transparencies, at the same time.
Use opaque color for impasto, or glazing over with transparencies, any process, any time.
Different reflectance behaviour for dense/diluted colors, enjoy the hue shifts as you mix.
Allow different light source and exposure control of the image.

If that phrase "for individuals" means "for individuals only", then it isn't GPLv3, but some bespoke non-free license.
My speculation: it was intended to mean: use it under terms of GPLv3 (for commercial purposes or not), OR contact to negotiate different terms.
But there's a built-in assumption that no commercial entity would _want_ to use it under GPLv3 terms.
I think it's more subtle than that:
