Palette Shader
A colourful city demonstrating a WebGL palette swapping shader. Here I show off some of the palettes and settings.

How it works: regular phong shading is done on the model of the city. The luminance of the fragments are then used to index into a palette texture to pick the final colours. A directional light hovers over the scene to create the nice variations in the colours.
I used three.js and TypeScript to make this. The code is free and open source.
