Do things still have color in the dark

i was laying in bed last night, and i looked around my room and
everything was pitch black. so i thought of somehting intersting. a
blue shirt is still blue when you turn the lights off. or is it? Color
comes from how light reflects off of something, so when ther is no
light, what color is it?

well your eye translates the reflecting light into that colour. so i guess to you, it has no colour?

Yes, it still has color. The shirt will absorb all the colors of visible light except blue, so that it appears blue to the eye. In the lack of visible light it still has the potential to reflect blue light, so it is still colored, just not visible. Light is also coming through in many other wavelengths, so it could still be a "color" in UV, IR, etc.

it would technically still be blue, it just isn't absorbing the light as much so it isn't as noticeable. Even if there was no light, it would still have the characteristics of being a blue shirt.

as it gets darker, you see less color because your eye is using rods instead of cones. the color of something doesn't change though, color is an intrinsic property of what segments of the visible light spectrum it absorbs.

In a truly lightless environment, there would be no color.

That's not necessarily true. Objects emit light, just not necessarily on the visible spectrum.

i dunno how relevant this is but your glasses don't work in the dark because they reflect light into your eyes so you can see clear so if there is no light then they aren't doing anything..and i don't know if your eyes even work in the dark because they work off of light too

Yes. but i dont exactly know why.
If a tree falls in for forest, but theres no one there to hear it, does it sitll make a sound?

no, if a tree falls in the forest and there is noone around to hear it, it does not make a sound

that just depends on your definition of sound. I think sound is the production of sound waves emanating from an object. So if a tree falls in the woods and no one is around to hear it, then yes, it still makes a sound.

sound is only sound once it has traveled through your ear and turned into electrical impulses that are sent to your brain, until then, said "sound" is just vibrations in the air

Agreed but really this is just an opinion question rather than scientific...

if your nose is full of boogers, why doesn't everything smell like boogers?
followups: do boogers have their own smell?
do you subconciously eliminate that smell from other odors, or does everything
you register as an individual smell have a tint of boogers to it?

There are 2 different types of colour: Light and Pigmentation.
The pigmentation colour of an object is not affected by the lack of light, its is simply that you are not able to perceive the colour of an object without the light reflecting from the object to your eyes.

you subconsciously filter out a lot of smells. The first time I ever went to my dad's work, it was sickening how it smelled. He works for Pfizer and grows huge vats of bacteria and stuff to be used for tests and for medicine. And bacteria reeks. After going a few more times, I didn't even notice it anymore. You get used to smells and your nose filters others that you don't like.

Boogers do have a smell. Pick a huge one and hold it up to your nose. It kind of reminds me of the smell of wood glue.

wow, i was just thinking about this the other day. I was going to make a thread about it. once in a while, dont you notice your own booger smell? do you ever just smell the inside of your nose?

in pitch dark, where no light can enter, nothing has color because objects cant absorb any light to reflect colors.

Haha, im glad you like it.
Sound's all about interpretation. It makes a noise, but you have to be able to interpret it, and if you can do that then it must have reached your ears

it has no color because there is no light to absorb/reflect into your eyes.

eyes use two different mechanisms to see, rods and cones. When light is really dim you are using your rods to see, which can't detect color, so yeah, in low light you see in grayscale. I dunno if thats what you were talking about, but thats that.

Does a falling tree in the wood make a noise if nobody is listening?

your eyes have 3 different systems when sensing light: photopic (cones), rods (scoptopic), and mesopic ( a combination of both). scotopic vision is active only in extremely dim illumination which you would call dark. color is nothing but a cortical perception, so you could say that in the dark, you can only see gray-scale so there is no color perception. on the other hand, you can argue that an object has certain electromagnetic properties which makes it the same color all the time. in low illumination, an object will still have the same properties as it does in bright light. in the dark there is just not enough light from a primary source to illuminate the second source, so not enough light is incident on our retinas to surpass threshold levels to stimulate a ganglionic response.
