Mass Block Configuration

[Eario]

Hello,
I am wanting to use this mod with the mod TerraFirmaCraft. Due to this mod adding numerous variants of all of its given ores, editing the displayed color for every version of each in-game ore to be the same no matter what variant of the same ore it is would be time-consuming and tedious, and closing and re-opening the game to set one variant in-game and copy-paste its color code to all matching ores in the json would be similarly bothersome.
I'm wondering if there's a good way to get a color code that would work for this mod with an outside tool, which would massively speed up this process.

Additionally, a way to mass toggle ores between being enabled and disabled would be very helpful.
