I've been having a lot of issues with finding those bloody (no pun intended) things as well, but after going through various of forums and looking for them myself.Basically, orange bloodroot grows underground, hanging from blocks of dirt. Although their rarity colour is 'common' they're actually 'uncommon', so go figure. You can also spot them on your map, so when you go roaming around the underground, check the map ever so often.

Bloodroots can even take unexpected left turns into a nightclub aesthetic or a more Roman coliseum-esque locale, but it all feels cohesive with the overall art direction. And each is backed by the thumping jam of a soundtrack that often acted like a renewing catalyst for my mayhem. Bloodroots, at its core, is a revenge story, and the stoic. One of North America’s all-time native wildflower favorites, beautiful Bloodroot, a member of the poppy family, rises in early spring with unique cigar-shaped rolled up leaves that eventually open into large, waterlily-like foliage.

The root appears as a red block, its shade being somewhat darker from crimson, so that helps!I also noted that having Cursed Sapling and Wisp helps you somewhat, too, especially the former. The Frost Hydra is pretty helpful too, as it helps you to make your map wider when you just spawn it around you. It can be tedious, but this way, I've found those roots a lot easier than before.I'm sorry for this being so late to answer.:(. Id suggest you just go spelunky and dont try too hard to find it. Basically all those dyes are collected on the run like optional. Cosmic rift sony.

You will be happy to find one, but dont try too hard or you will go insane. Those plants etc are random so all you can really do is explore and run around and hope for the best. But going out only to find bloodroot is not good idea and bound to frustrate. Try to look out for several things and collect em while you have fun exploring and digging.Other option would be trading with friends you trust and whom earned the items legit.It can be fun to trade one color of dye vs other with your friends for example!Good luck on the search.
