I'd like to see a fluid solver that could model the 2D pattern of supercells utilizing the palettes that BR and BV use.
The base reflectivity and enhanced echo tops palettes are similar but differ in few ranges of color.
supercells and bow echo / squall line patterns resemble some of the disconnected Julia set patterns and some of the IFS fractals. Given the 500 millibar jet stream direction and surface wind directions and 850 millibar level winds and the shear that goes on produces flame like patterns that are unmistakable.
Also I've saved the same palette patterns as Xaos palettes and they never save or reload the palette with the same colors I had chose and set in Xaos.
Hi, thanks for your comments! Please can you share your palette pattern files? XaoS palettes may work differently as you expect.

When I had that picture generated I saved the palette which I just posted. But it will not load those same colors. Use the potential coloring setting and 1/mu Also I haven't noticed a (1.0 - potential) setting for better transitional slopes.

I'm thinking it might be possible to apply a Base Velocity palette to the binary decomposition renderings too.
I've determined it is a bug where the first two palette entries are being substituted with different colors when it is loaded from a saved palette. GIMP Palette Name: XaoS_Palette Columns: 16 # 0 0 0 color_0 85 0 255 color_1 0 170 0 color_2
When loading the correct entries above the result is: color_1 is being replaced with 0 85 0 and color_2 is being replaced with 0 0 170 so it seems that color_0 isn't being properly parsed. This is when Outcoloring mode is set to "potential" and plane is set 1 / mu. I'd really like to see how 1.0 - potential looks like too.
