The suggestion. if you were colour coding everything, I could at least see a point - even though i wouldnt agree with it. As it stands, your suggestion just looks like a daft change with zero reasoning behind it.
Now, if you wanted to request very obvious texture diffferences for the colour blind, that could be something I could roll with, vote for and push (I'm not colour blind BTW). Right now, the oddity of the roids composition and the confusion it can cause is one of the reasons to still explore:
"oh i need to make this, which ore is that?... thats the black roids, right? Oh, look, pirates!"
Yeah, for experienced players, those arent a problem, but for newbs they are. Now, if somehow bigger, harder pirates were added and you suggested they guard the more "premium" ores (fertikeen lets say)... then again you would have a point. right now, you have some weird colour banding. Sorry for the typos and I hope that makes some sense.
