Add https://jps-34.github.io/Badassium238/ under Resources > Updates > Manage Repositories.

 Badassium238 1.2.6 (PixInsight 1.9.4 and later)

Breaks the two-colour look of SHO images: finds which emission lines end up with the same hue, then gives each line its own colour (for example SII red, Ha gold, OIII blue) by a hue-only rotation at constant luminance, with live preview and optional palette presets. English or French interface. The original image is never modified. Installs under Script > JPS > Badassium238.
