Question

My Tshirt I was wearing today was bright red. now its laying on the floor in the dark its a dark blacky brown colour...so..what is my t shirts true colour?

Light is the variable so if you take that away you are left with black. This implies that everything is actually black... confused.

Answer 1

Hold the shirt under a black light. It will give the best representation of the shirt's true color.

Answer 2

Ok, well strictly speaking there's no such thing as colour, things absorb or reflect light. We see a very narrow part of the electromagnetic spectrum a range of 400 to 760 nanometers. Differences in wavelengths within this range the eye percieves as colour.
When all possible wavelengths of light reflect off something at once the eye sees the colour white. When no (or very few) wavelengths of visible light reflect the eye sees the "colour" (actually the lack of colour) black.

Does that help? Its just different wavelengths.

Answer 3

black is the absence of colour,

ur true tshirt colour would be viewed under white light as white light contains all colour frequencies, whereas black contains none - this means ur tshirt cant reflect any colour to your eyes in the dark

Answer 4

The color of an item you see is the color of light it reflects. So every wavelength of light available and reflected by the objects is the color you will see.

Just to mess with your head a little, a true red shirt is actually every color but red. The RED shirt would absorb every color (wavelength) of light and reflect only the red wavelength of light.

So to answer your question the light available is lacking the wavelengths of light you saw reflecting off of the shirt previously.

Answer 5

Light is a big factor is Color.
Our sun puts out most of its energy in "visible light" so our eyes evolved to see visible light.
Now a color of an object means that the object absorbs all other visible color excpet for the one u see.
Meaning if an object is Blue it is absorbing all the other colors of the rainbow except for blue, and is reflecting blue.

When an object comes in contact with an object of a different color it can merge creating a different slightly combined value of color.
And all objects are colorless till light hits them and they reflect certain color only.

Answer 6

look at your bright red t-shirt through a red film, like the red lens of 3D specs. then you will see, a white -ish t-shirt.

then look at it through the other lens which will be blue or green.

Now after that, what colour is your universe?

and are you more confused?

Answer 7

freq.of visable light denotes colour

Answer 8

exactly in true fact colors dont exist its just your interpretation of different electrmagnetic waves by your brain

Answer 9

all objects have no color until light reflects off them

Answer 10

sounds like u have been sweating too much
