Shrimp have multiple color recptors because their brains are too primitive/rudimentary to combine input from more than a single receptor into a composite color. The result is that 12 colors (or however many receptors it is) is the total number of colors they can see.
They also see in UV and can see polarized light
and can see polarized light
So can we. It’s also like to point out that seeing polarized light is different from being able to tell that it is polarized. Which we can still do, just not as well
How can I tell when I’m seeing polarized light?
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.

Is there? How do you determine whether the machine doing the measurements is real?
The face punch method, (not a personal attack just a rather crude if effective philisophical tool) aka if I repeatedly punch you in the face you have a hard time continuing to argue that my fist is not real, or at the very least real enough for practical purposes. Personal involvment makes the situation a lot less abstract.
Oh, I never argued that fist are not a good way to determine reality, but calling your fist a machine is cringe.
Funny – just this week I ran into the concept of Solipsism for the first time in my life, and now this post.
I sincerely doubt you ran into anything given that you don’t exist.
