To "make" any color involves one of two basic processes.
There are e missive or additive, and absorptive or subtract methods to create color.
When using e missive or light sources to create color, i.e. like a TV or computer monitor, three primary colors are used, red, green, and blue.
This is additive color production. Each of the three primary colors add together to create the final color. If you use a magnifying glass, or even a small drop of water on your computer screen, you will see only three colors; red, green, and blue. Combined in "equal" amounts, your eyes perceive white. I say "equal" because the percentage of each color varies in order for the human eye to perceive "white" as the eye's sensitivity to color varies by wavelength or individual color. The actual levels of red, green, and blue to make "white" are not equal for the human eye.
Now the flip side. As monitors emit light, ink can only subtract, or absorb light. Thus the primary colors for ink, are the opposite inverse primary colors of cyan, magenta, and yellow.
Because inks subtract color, the inverse colors are used as compared to a TV or computer monitor.
Now, on to your question
The reason a red shirt, or anything red for that matter appears red, is because the dye/substance absorbs all other colors i.e. reflects the remaining colors. So a red shirt, in "color space" is really absorbing cyan, and reflecting magenta and yellow. The two together are perceived as red to the human eye. The exact shade of red depends on the exact amount of the three colors being absorbed.
One could say the shirt is only reflecting red. However, as non-emitting color sources only absorb light, the red shirt thus must be absorbing cyan, and reflecting yellow and magenta which together combine to make "red".
The theory of color is quite complex, but this is the basic reason something red, be it a shirt or an apple looks red.
In theory, red+green+blue = white. And cyan-yellow-magenta =black. Inverse operation of emissive and abortive color creation.
In real life, inks are not perfect which is why color printers have four colors, cyan, magenta, yellow, and black because c-m-y tends to give a dark brown and not black. So adding black allows the printer more ability to create all the colors it needs to and saves color inks which alone cannot create a pure black.
Anything not emitting light is a subtract system while things emitting light are additive systems.
What else can I help you with?
What will a blue shirt look like when it is in red light only?
When a blue shirt is in red light only, it may appear very dark or nearly black because the red light does not contain the wavelengths needed to reflect the blue color of the shirt. Instead, the shirt will absorb most of the red light, causing it to appear dark.
Juan was wearing a bright red shirt in a very dark room What color did his shirt appear to the people with him in the room?
The red shirt would appear darker than normal in the dark room, possibly looking like a darker shade of red or even black to the people with him in the room.
What kind of light does a red shirt reflect?
A red shirt primarily reflects red light. When white light (comprising all colors of the spectrum) shines on the shirt, the red fabric absorbs all colors except red, which is reflected back to our eyes, making the shirt appear red.
What colour would a red shirt appear to be under blue lights?
purple-redish-blueish need more acuracy plz :)
Is white light reflected through red shirt?
A red shirt appears red because it absorbs most colors of light and reflects red light back to our eyes. White light contains all colors of light, so when white light hits a red shirt, the shirt absorbs most colors and reflects red light, making it appear red.
What will a blue shirt look like when it is in red light only?
When a blue shirt is in red light only, it may appear very dark or nearly black because the red light does not contain the wavelengths needed to reflect the blue color of the shirt. Instead, the shirt will absorb most of the red light, causing it to appear dark.

What will a green t-shirt look like under a red light?
A green t-shirt will appear darker and less vibrant under a red light due to the way the human eye perceives color. The red light will make the green shirt appear more subdued as the red light will reflect off the green fabric and alter its appearance.
Sam is wearing a white shirt a red jacket and green trousers to a night club what will his clothes look like in a red spotlight?
Under a red spotlight, his jacket will not show up because it is red. His white shirt will appear red and his green trousers will appear black. This is because The red jacket is the same color as the light. His white shirt will turn red, since white reflects all colors, and since red is the only color, the white shirt reflects that color. His green trousers will appear black because there is no green that reflects off his trousers.
Is white light reflected through red shirt?
A red shirt appears red because it absorbs most colors of light and reflects red light back to our eyes. White light contains all colors of light, so when white light hits a red shirt, the shirt absorbs most colors and reflects red light, making it appear red.
What color stage light would make a red shirt and blue pants appear black?
A cyan stage light would make the red shirt appear black because cyan is the complementary color of red. A yellow stage light would make the blue pants appear black because yellow is the complementary color of blue.
Why is the stage light color red when a red shirt and blue pants appear black?
The blue pants appear black because they are absorbing the red wavelengths. The shirt must not be the same color as the light, because using basic knowledge of how light works, if it really was red along with the stage light, it would appear red as well. Therefore, all of these clothing items are absorbing the light and not reflecting it back as the colors they should be under white light.
Why does a green shirt look black in red light?
The reason the shirt appears red in white light is because it is absorbing all other colours apart from red which it is reflecting into your eyes. When in a green light there is no red component of the light to be reflected so the shirt absorbs all the available light which makes it appear black.
Why does a red shirt appear orange?
Red and orange light probably have similar wavelengths so, in poor light, red seems to be orange. To be honest, I thought that orange looked red in poor light. If it appears orange, then why in the world do you call it a "red" shirt ?
What color a red shirt appear when the room lights are turned off and the room is entirely dark?
When the room lights are turned off and it is entirely dark, a red shirt will appear black or very dark. This is because color perception relies on light; without any light to reflect off the shirt, our eyes cannot detect its red color. In complete darkness, the absence of light means that the shirt's color cannot be seen.
