I know you speak with some scientific reasoning, but in this sense, aren't all colors abstract, moreover, subjectively perceived, maybe also made up... and in general, as everything around us is made up, unconsciously influenced by our personal perception... And isn't every color invented by us to save us from darkness, or from the coldness and indifference of white... 🤔
I think I'm very sleepy now, so I started going off on some unrelated topics 😂
