Why do red object's look black in blue light?
Red and blue are primary colours therefore they do not contain any other colour. When a blue light is shone onto a red object, all the blue light is absorbed by the red object, and as no red light is being shone for the red object to reflect, no light will be reflected from it and it will appear to be black. It is important to remember that physical colours will only reflect it's light colour equivalent. All other colours are absorbed. So red will reflect red, green will reflect green, and red will absorb green and so on.
What colour would a red object seem to look like if you only shined green light on it?
The object would be black, because red cannot reflect green light so no colour is reflected of the object.
How do colored objects look under colored lights?
If the light is or contains the colour the object it is striking, then the object will appear to be the colour it originally is. If the light is not or does not contain the colour the object it is striking, then object will appear black. This is because an object will only reflect the light that is the same colour as it, all other light is absorbed. For example: Red, yellow, magenta, and white light will make a red object appear red as they all contain red light. Blue, green and cyan light will make a red object appear black.
What colour is a white object under red light?
The white object will look red because the white surface reflects all colors and since only a red light is used it will only reflect red.
What colour will a white object appear if only red light was shone on it?
Red. The colour of an object is determined by the wavelengths of light it reflects and absorbs, and a white object is one that reflects light across the visible spectrum. If only red light shines on it, it will reflect that light. In contrast, a black object appears black because it doesn't reflect any visible wavelengths, so would still appear black. Any object that doesn't reflect the wavelength of light you're using (eg blue objects) would also appear black because it isn't reflecting any light.

Can object reflect both red and blue light?
On stage in a theatre red light shines and clothes appear red, blue light is shone an clothes appear blue, what colour are they?

What colour is a red object when red light shines on it?
Red light shining on an object that reflects primarily red light will be red
What colour would a green object look under a red light and why?
A green object would look blaack in a red light because coloured objects absorb all colours except the colour they are, so a green object absorbs 6 colours (red, orange, yellow, blue, indigo, violet) and reflects 1 (green). In this situation, there is no green light to reflect and it can't reflect other colours, so it looks black. :)
How do you know that most objects reflect more than on colour of light?
You can diffract the light reflect from the object and see what range of spectrum is absorbed and what is reflected. It is to mentioned, human had trichromatic vision. We base our vision of colour from the portion of red blue and green. The real colour in spectrum is however continue of colour from red to violet. By having only 1 colour of light reflect, the object had to specifically absorb exact the other 2 portion of light human can see which is extremely rare for natural objects without specific design to absorb light at exactly cover the other 2 spectrum human can see. So it is most objects would reflect more than one colour of light.
What colour of light would reflect from a red pigment?
PINK
What colour will a yellow object look in red light and why?
It will look red. White light is made up of a spectrum of many colours. The primary colours are red, green and blue. An object (in white light) appears yellow because it reflects red and green light but absorbs blue light. In red light, the same object will simply reflect the red light. Since there is no green light, the object will appear red. (A mixture of red and green gives yellow)
What colour does a white ball look in red light?
It would appear to be red because it can only reflect the red light.
