Is this why hunters wear blaze orange? Other hunters can see them, but the deer see green like foliage?

    Yup. Also because the biggest danger when you're hunting is other hunters

    Well I knew the second part. I also knew that deer rely on scent far more than vision to spot predators. What I didn't know is why hunting laws specifically call for the use of blaze orange (also fluorescent pink). Not the caution yellow or that greenish yellow you see a lot in construction and high visibility garments, but specially blaze orange. It makes perfect sense if the orange still works as camo from the deer, but is extra visible to other hunters. That's like a best case scenario color.

    So then why don't hunters just hunt in tiger stripe jumpsuits, something that would make RiFFRaFF blush

    ‘This is some grade-A bullshit.’

    • Deer and wild boars, probably

    The real question is what color they see themselves as. “I’m bright orange and they still can’t see me? The fuck?” Or “I’m green and should blend in perfectly, but that human is looking right at me!”

    Same as the deer, dichromatic red/green colourblind. Can't differentiate between red and green

    A tiger does not know it's orange

    If they were just green then they'd be able to hunt us too, morons.

    Just say "can see red" and "can't see red"

    It's interesting to see how things look for various types of colour blindness.

    I ran across this android app on another comment thread (on game accessibility I think). It's fun to play with.

    I dont really see a difference....

    So ... you're already aware of of your red-green blindness or just finding out?

    https://en.wikipedia.org/wiki/Congenital_red%E2%80%93green_color_blindness

    It's quite common in it's mild forms. I never noticed it till after shop-class when I was really good with the theoretical aspects of electric circuits, but on the practical pieces I always put in the wrong resistors ... because they were colour coded with shades of green/red/brown that kind of look the same for me. I even argued with my teacher that I did in fact put in the correct resistors, but he won because it actually wasn't working ...

    Only a few years later when doing a vision exam during mandatory conscription that they just blatantly asked me if I was colourblind ... and at first I was like .. "no?". But they said that results said I was ... and suddenly shop class made sense ...

    Is the tiger similar color to the grass for you?

    Are orange housecats remotely stealthy?

    The tiger no. But put that same hue of orange next to some greenery without any context and it might.

    The brain is really good at compensating for colourblindness. You could probably paint a tiger green and I'd tell you it's orange because I know tigers are supposed to be orange.

    I, too, saw that factoid in a crossword yesterday

    Some humans and possibly other species are tetrachromats

    In humans, effectively no. Anyone claiming to be a "tetrachromat" is really trying to say they're half-colorblind, that they have some normal and some mutated green cones. If they do, the mutated green cones basically don't work.

    Mantis shrimp have 12 different types of cone cells to our 3. Now, some people want to think that they either see a wider rainbow, or have significantly greater resolution or depth of color perception than we do. The former is kind of true, the latter very much isn't. Humans have VERY sophisticated brains, we use more brain matter than the mantis shrimp's entire mass to process vision. We do all kinds of Nvidia branded shit to turn the three color signals from our eyes into the full spectrum of colors we perceive. Meanwhile, the mantis shrimp sees in EGA. They see 12 colors...only, and at a much lower resolution than we do with their compound eyes.

    They see 12 colors...only

    I've seen it said that they gain in vision speed by saving on the complexity. Conversely, we don't properly see a baseball flying at us, but have machinery predicting its trajectory so the brain fills in the gaps.

    What are the 12 colors that mantis shrimp see? We should be able to name them!

    I thought they were orange because it hides them in the dry grass or whatever in the dry places where they live.

    What does blood look like to them?

    Very different vibe when the tiger mom tells the cubs to "eat your greens."

    Also, do cats eat grass so they can pretend they are eating little blood sticks?

    My cat eats grass because she likes a salad before dinner, I think.

    Anyway, I know she prefers real grass (it's maybe crabgrass, I think? It crops up unasked-for in my balcony plant pots) over "cat grass" (oat/wheat/rye from seeds) growing in the kitchen window, but will eat both.

    And it doesn't make her vomit, it just helps her poop.
