algorithmic modeling for Rhino

Testing an algorithm for interpreting colours with high-dynamic range channels. Normally if the RGB channels are clipped to the (0,1) range, colours with very bright channels tend to primary or secondary colours. Here instead I'm treating channel values outside of the (0,1) range as errors that need to be diffused to the remaining channels.

The video shows a section of constant red through an HDR RGB colour cube. Red starts out at -1.0 and ends up at 2.0, while green and blue go from -1.0 to 2.0 left-to-right and bottom-to-top respectively. The square in the middle shows where the blue and green values fall within the standard (0,1) range.
