    Brain working as expected. Thank you for the confirmation. I did have some doubts before.

    Fun fact! Since we (primates) have three cone cell types, we only really see three colours (red, green, blue). The rest are illusions. Some animals, like some fish and birds, have four or five cone cell types.

    This means that for animals that have a cone cell type for yellow, a sunflower displayed on an LCD screen will not have the same color as a real sunflower. The screen will show a mixture of red and green (which we perceive as yellow) but it won’t actually be yellow.

    Colour is just an illusion caused by objects absorbing some frequencies of light and reflecting others into the photo receptors of your “eye”.

      If I had a nickel for every time somebody asked that…

      I’d only have one nickel.

      … but it’s a girl nickel!

        I remember when I learned about the possible existence of a girl nickel. It was right before creating this reply to it.

      Good question! Some people will probably cite the electromagnetic spectrum, but in this case the scientific principle is much simpler. It’s called “because I felt like it”
