This patch allows you to set a different custom palette for each of the 7 castle destruction sequences. Cutscenes that have no palette set will use the vanilla one instead. The insertion process is pretty easy: you just need to export the .mw3 palette file with LM, then add a line in the castle_cutscene_palette_settings.asm file. Check out that file for more info.

A fresh coat of paint can go a very long way towards livening up the otherwise stale vanilla castle cutscenes. Be aware that there are some forced palette updates that will always override your settings, such as the background color flashing in Iggy's cutscene which will always end up blue. Much like in-game, Mario's palette is updated on-the-fly, so attempting to change the latter colors in palette 8 will have no effect.
