I don’t think having a Creative world is cheating, just a time cut and a way to have all the colors you want. But as I cannot bring the blocks into the rest of the universe I don’t buy them. I do buy regular Sov’s.
I have to agree at the rate the colors unlock I will be dead and gone before they all unlock.
This IMO is the crux of the issue with unlocking colors. The algorithm needs to be modified or removed.
Who cares if you get clashing colors? The color changing Exo’s do this sometimes. I have been on some Sov’s that I was like what are these awful colors??? But just because I don’t like them does not mean others will not.
