Hello /sci/ I have a quick question for you. Imagine that someone

light (photons) is additive because of how our eyes/brains process it (eg RGB pixels from a monitor can make many colors)

red light coming from deeper in skin, green light coming from top layer of skin, so you'd see yellow

but if you mix actual physical pigments (bulk phase), what happens is their absorbance regions overlap until there is no wavelengths of visibile light that they transmit. so basically there are an "infinite" amount of molecules all absorbing different EM bands, and there is no photons that make it to your eyes, so you see black.

when you take paints that appear black and smear them across a white surface, often times you will see their constituent colors come out because suddenly theres more of molecule A than B, so some color not fully absorbed by B gets through.

here's an example of black ink spread out using TLC

So - if i understand it correctly - light would "come back" yellow, but because it has to travel "through" layer of molecules it would come back as slightly darker (depending on amount of light i'm shining)?

it would be because there are both red and green photons entering your eyes and striking your photoreceptors within a very close distance of each other, so your brain interprets this as yellow

a yellow pigment on the other hand could just transmit yellow light normally

so they could either have yellow skin, or thin layers of red and green skin, and you'd see the same thing

sorry i explained it badly in the first post there

sorry and i should explain that yellow light would trigger both your red and your green photoreceptors in your eyes

so light can have a natural wavelength corresponding to the color we see as yellow

and it can also combine the two wavelengths equal to the colors we see as red and green, and our brains would see the same thing

heres a quick diagram.

and what i meant about actual physical pigments is that black inks appear black because they absorb all the light and none gets reflected to our eyes, and our brains process it as black

green = blue + yellow
green + red = blue + yellow + red
blue + yellow + red = brown
