How can one claim an ownership of a colorway/keyset?



This isn't the first time this type of drama occurs with keysets. With established conventions on alphas and modifiers, there is a limit to how ideas and colors can be used. My personal belief is that, no you can't lay claim to color combinations, the whole execution matters, and you actually have to follow through. Straight copies are likely to not be well received, and ripping off original novelties or icons without permission is unacceptable.The last post by @joinhandmade on the Starry Night IC was May 31st 2016. The last post in the thread was Oct 2016. That project looks dead. Esquimo posted a different interpretation than yours. I can see why he might feel aggrieved, but I wouldn't assume you copied him. It seems like a case of bad timing, and as I said above, neither of you can claim to be first.If this meoldrama didn't sour you against the project and you want to move forward, you could message joinhandmade and see how he feels about this. If there is no ill feeling, go forward with your own interpretation if that's what you want to do.Esquimo can do likewise if that's what he wants.
