Damage color point.point nft mint or point barrier

hello to all I come back to this subject because I find the color of the damage points strange, many say that it is the barrier points but the colors do not match
to break a purple barrier the orange points pass
for a yellow barrier and not an orange one, that’s where it’s wrong
I have the spell to break the yellow barrier (yellow square under spell on bar item) purple dots appear
for me it’s not barrier points it’s the points to minter the nfts if you want a rare nft do only blue dots in a dungeon
an epic only made purple points and I think that if we reach a certain number of points in the dungeons by cleaning them completely to be able to reach the number of points necessary to activate the mint
What do you think?
