This reminded me of https://www.reuters.com/article/electronicarts-zynga/update-... , but alas they settled outside of court so we didn't get a precedent on digital palettes in this particular case.
I bet Pantone believes they can copyright a color palette, considering Adobe just pulled their colors out of Photoshop.
Stary Night is in the public domain which is why you see so many near copies in corporate works.
The other is amusing in light of this case: https://www.supremecourt.gov/DocketPDF/21/21-869/213328/2022...
I'm going to need to see a source on ripping the same color palette as being illegal.
