Vasco Basquéhas just released a new brush set for Krita, meant to simulate watercolor brushes. It’s an interesting thing to happen, of course, because until Krita 2.0, we had an actually physics-based watercolor brush engine in Krita. We lost that because the code became unmaintainable… Then during the early 2.x releases of Krita we had actual, physics-based color-mixing. We lost that because the code became unmaintained — and it turned out, in the end, that it wasn’t what artists wanted in any case. Though we get requests for a color mixing palette now and then!
