Well yeah, that thought is important. While apples do have an objective color in the sense that physics teaches us that electromagnetic radiation with a certain frequency is more or less likely to be absorbed/reflected, we can only perceive a subjective color.

I personally define reality as any measurement that a machine (computer or robot) can take. As such, there is an objective reality. But also, most people mostly act on emotion and not based on real data.

But also, this isn't a meme. It belongs in the philosophy or science memes community.
