Many paint programs simply use RGB color space (native to digital systems) and alpha blending in their tool. Some complain Blue and Yellow don't make Green but a muddy gray.

Color MixingĪnother aspect Adobe put effort into make digital paint more realistic is color mixing.

Look at how organic are the oil paint and pastel strokes in the following video:īoth shows ridges and color mixing, but which one you say is more organic or feel like real oil paint? If you ask me, I think Project Gustav / Fresh Paint is better in capturing the streak details and is closer to what real paint does. My main contribution there is the oil and pastel model found in Project Gustav, which later is productized as Fresh Paint. My work addresses the problem of missing details in oil or pastel modelling found in many other paint apps. We also beg to differ when they say the oil paint simulation in Fresco is more realistic. I as a Computer Graphics Researcher & Developer previously worked at Microsoft. In contrast, Expresii can render the artwork in much higher resolution with details. Lastly, you can't see subtle details in Fresco's rendering when you zoom in. This keeps Fresco from being able to create large-area flow patterns - a major contribution to the charm of the watercolor medium. Another important point is that our flow is global instead of being restricted to stroke vicinity like in Fresco.

Such modeling often gives artificial-looking 'turtle-back' patterns. Close examination of Fresco suggests that they use expanding 'waves' to model spreading watercolor. Second, we use Computational Fluid Dynamics to model wet watercolor for really natural flow patterns. Fresco uses stamp to model the watercolor brush, so the above natural brush manipulation is simply not possible. making a gradient by loading different colors along the brush tuft and tilting your brush just like in real life. Because it's a 3D virtual brush that you can wield, you can e.g. The above video comparing the two apps' watercolor simulations and illustrate several differences. First, we use physics to model the deformation of our virtual brush, allowing subtle variations in the strokes. The statement was made by their Chief Product Officer Scott Belsky. We feel compelled to compare their and our watercolor simulation: Watercolor At Adobe Max 2019, Adobe claims Fresco's 'Live Brushes' are more accurate and realistic than any other apps out there.
