Items Corruption/Crimson/Hallow detection potions

[BrandSilven]

In my non-modded worlds, I've been wanting to control or at least contain the spread of these biomes, but sometimes a small block will remain hidden, continually spreading it without me being able to find it. So, I would like to see potions that make Corruption, Crimson, and Hallow blocks that spread those biomes glow or sparkle, similar to how a Spelunker potion or Danger Sense potion works. Having an in game item to help detect those (ideally they'd be separate potions, but one that does all three would be fine) would be a fun, albeit fairly minor, tool to help combat them.

Thank you for your consideration.

This is a really good idea and I think that it could possibly use the stone block and/or sand block variants in the potion crafting if this were added. I hope this gets in because this is definitely a thing I would like to see.
