AI and machine learning aren't necessary at all. You 'just' have to empirically measure a few constants that describe and bound the various nonlinearities of different real pigments, and then plug them into a relatively straightforward paint mixing equation. Paints have predictable mathematical properties in terms of what color they produce when mixed; they just mix nonlinearly, which is counterintuitive for people who have not practiced mixing paint a lot. Photoshop and the other comparison programs on the page illustrate the linear mixing that most people intuitively expect.
