This is really helpful, thanks. To add something maybe people already know: colors “change” depending not only on camera and lighting, but also on context. I have a grey rug that looks blue—definitely BLUE—when blue furniture is placed on it, and it looks GREY—deep, steely GREY —when dark grey or black furniture is placed upon it. My antique oak dresser is dark, deep, warm brown, but when placed in certain contexts, other colors will bring out the yellow tones in it. Shopping at home in COVID times, I’ve been taking pics of my own stuff in lighting that mimics the pics in this forum, and pics of samples in different lights, and comparing them all on Pinterest ( no I do NOT work for Pinterest). When one takes into account color variation in leather and all these factors Duane has brought up, it just reminds me that I’m gonna get an APPROXIMATION of color before the leather hits my floor—and like Duane said—it’s like the excitement of opening a present on Christmas.
