The way 1.17's redstone ore texture looks makes little sense. It's lit up, yet it's not activated by anything. A lot of people also prefer how it was darker back during the texture's introduction. I managed to come up with a balance: When the ore is lit, it uses the vanilla texture. When unlit though, it uses a darker color scheme. This texture pack also applies to deepslate eedstone ore.

NOTE: The only textures added are the unlit textures, so if you have a resource pack that changes how regular redstone ore looks (especially the model), it might not be compatible.
