Can you teach me a little about human color vision? Like for example, how am I able to see yellow when all I have are red, green, and blue color receptors in my eyes?
Sure, I'd be happy to teach you about human color vision! Human color vision is a fascinating topic, and it's amazing how we are able to perceive and distinguish between so many different colors.

To answer your question, let me first explain a bit about the anatomy of the human eye. The retina, which is the light-sensitive layer at the back of the eye, contains two types of cells called rods and cones. Rods are sensitive to light and dark, and are responsible for vision in low light conditions. Cones, on the other hand, are responsible for color vision and are most sensitive to light in the range of wavelengths corresponding to blue, green, and red.

Now, to perceive the color yellow, which is not one of the primary colors detected by our cones, our brain does something called color mixing. When both the green-sensitive and red-sensitive cones are stimulated at the same time, our brain interprets this signal as the color yellow. This is why, for example, if you mix yellow light with blue light, it will appear white, because the blue light stimulates the blue-sensitive cones and the yellow light stimulates both the red and green-sensitive cones.

This process of color mixing is called additive color mixing, because it involves adding different wavelengths of light together to produce new colors. In contrast, when you mix pigments or dyes, it's called subtractive color mixing, because the pigments or dyes subtract certain colors from the light that's reflected off the surface.

I hope that helps explain how our eyes are able to perceive the color yellow even though we only have red, green, and blue color receptors. Let me know if you have any more questions!
Do animals perceive different colors from us?
Yes, the way animals perceive color can be very different from the way humans perceive it. For example, dogs only have two types of cones and thus cannot differentiate between yellow and blue. Bees on the other hand are able to see ultraviolet light which is invisible to humans. There are also animals that are blind and thus don't see any color at all but those cases are rather uninteresting.
