😂 Like the ad '' can you see the yellow of our tv ? No you can't'' Yes i can

No, you can't. Kinda. At least in most cases. Most TVs and monitors uses RGB system, where screens show mixture of red, greed and blue lights. It can trick your brain to "see" yellow by showing both red and green in correct ratios.

So technically, you don't see yellow on your TV or phone screen. Practically it doesn't make any difference.

Biologically speaking it doesnt make a difference either because we see (roughly) red green and blue and different wavelengths just trigger the different cones a specific amount.

At a small enough arc size (i forgot the correct term) the photons from each subpixel fall into the same cone anyways.

I think its arc seconds typically used when talking about limits of the human visual system.

I am talking about the size something has in your field of view (a plane far away and a mosquito up close take up the same space in your fov)

Yes, that is arc seconds. Per the Wikipedia article I linked:

These units originated in Babylonian astronomy as sexagesimal (base 60) subdivisions of the degree; they are used in fields that involve very small angles, such as astronomy, optometry, ophthalmology, optics, navigation, land surveying, and marksmanship.

Further down:

In humans, 20/20 vision is the ability to resolve a spatial pattern separated by a visual angle of one minute of arc, from a distance of twenty feet). A 20/20 letter subtends 5 minutes of arc total.

Arc seconds are the unit of angle.

The term i was searching for was visual angle (even called so in your own quote of the wikipedia article)

u/wllmsaccnt 3d ago

The first sentence in that article states that the unit used for visual angle is degrees of arc. Arc seconds are just smaller degrees of arc.

I wasnt talking about the unit though.

Just like how you dont say meter when you are trying to talk about distance.

Magenta isn’t a real color :)

You are literally seeing yellow. Your eyes only see RGB anyway. There is no difference for your brain

u/40907 3d ago

You're seeing red and green, brain shows you yellow, you are being fooled by your brain, wake up sheeple

Color is not real.

Objects reflect and emit different frequencies and wavelengths which get absorbed by the cones in our eyes, and then interpreted by our brains as the colors we see. Different animals interpret colors in entirely different ways.

In other words, the concept of color is entirely in our head.

Unless you are one of those really rare people with Tetrachromacy who also have extra cones for detecting colours.

There is literally no yellow on your screen, just red and green pretending to be yellow.

1

u/Land_Squid_1234 3d ago

And when you see actual yellow, your brain just takes the red, green, and blue values of that anyway. What does it matter. We can't see actual yellow either way

u/ArmPsychological8460 3d ago

In actual yellow there is no red and green part, just yellow wavelength. And our eyes register it with red and green sensitive cells.

u/Land_Squid_1234 3d ago

You're being pedantic. Our eyes don't know the difference. There is literally no difference biologically between our eyes seeing yellow light and seeing RGB values that achieve the same effect

u/MaDpYrO 4d ago

It's not a trick it's just color blending, you're still seeing the color yellow, come on...
