nice try, but adobe got in the game long ago :) https://color.adobe.com/explore/newest/?time=all
Applying the same logic: "Google shouldn't have built their search engine because Alta Vista and Yahoo got in the game much before them." It is nice of you to point out an existing product which is similar. But isn't it better to encourage (or provide constructive criticism) rather than dissuade this?
not always. i'm all for the "theme and variations" style of software development, provided the variations offer something distinctly novel. that doesn't seem to be the case here.
