Inks mix subtractively — great transparency, easy to implement.

Not perfect though: greens still look a bit too digital. ✒️

This technique rebuilds the image by mixing color layers with MixBox lerping — a powerful color grading method that lets you target specific hues. Each layer defines a color gamut, and the algorithm picks the closest match to the desired color.

Watercolor shaders often look too digital, using Mixbox-inspired pigments makes them feel natural, like real paint on paper.

• Markers
• Uses CMY
• Works OK because marker ink is transparent
• Easy to implement (Same basic idea as mixing layers of watercolor)

Crosshatching + Mixbox mixing = pigment-like rendering. 🎨
The hard part? Deciding how much of each color to layer.
We use golden section search to minimize the error and make the final result match the image we want

When working with a limited palette, we have an endless variety of options to create different emotions. This is why realism can be very boring in comparrison.

When quantizing color in stylized effects, one problem is how bad the greens look. Computer green is the most annatural color (followed by computer magenta). A cheap trick to combat this is to simply shift greens towards yellow or cyan.

This is another experiement trying to see if we can capture something of van Gogh's style. This version applies the water color effect to the previous effect.

This is an experiment on the way to create a van Gogh filter.

While prototyping the tech we use in the videos, a lot of fun ideas come up that are too random to use.

Here is one that uses a 3D texture, some smooth noise, and cross-hatching to create the effect.

For stylized rendering with few colors, we have many ways to choose which color to use!

Here are some examples.
