LGBTNT

This is a simple resource pack that uses blockstates to apply random TNT pride flag retextures to placed TNT. If you would like to, for example, only make it use the pride flags that apply to you, you can edit the TNT blockstate file. (assets/minecraft/blockstates/tnt.json)

You can find more info about currently implemented flags in the version.
