Red light shining on an object that reflects primarily red light will be red
A red object reflects red light and absorbs other colors of light. When white light shines on a red object, all the colors of the spectrum are absorbed by the object except for red, which is reflected back to our eyes.
When red light shines on a red object, the object will reflect the red light and appear red. If white light shines on a red object, the object will absorb all colors except red, which it will reflect, making it appear red as well.
A blue object appears blue because it absorbs most colors and reflects blue light. However, when a red light shines on a blue object, the blue object would absorb the red light and reflect blue, so it would still appear blue.
When light shines on different colored objects, each object absorbs certain wavelengths of light and reflects others. The reflected light is what we see as the color of the object. For example, a red object absorbs most light wavelengths except for red, which it reflects. Therefore, we perceive the object as red.
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.

On stage in a theatre red light shines and clothes appear red, blue light is shone an clothes appear blue, what colour are they?
If the light source is truly cyan, the red object should appear black. The object is red because it reflects the red portion of the white light spectrum. With no red wavelengths available to be reflected, the object will have a lack of color (i.e., black).
A blue object appears blue because it absorbs most colors and reflects blue light. However, when a red light shines on a blue object, the blue object would absorb the red light and reflect blue, so it would still appear blue.

The red car will appear red, as the yellow light will be absorbed by the red pigment of the car and only red light will be reflected.
A "white surface" is one that reflects all colors of light. That's why it looks white when a white light shines on it, and that's why you call it "white". If only red light shines on it, then it looks red.
The object absorbs most colors in the white light spectrum except for red, which is reflected. This reflected red light is what we perceive with our eyes as the object's color.
Red objects reflect red light and absorb other colors of light. This means that when white light shines on a red object, the red wavelengths are reflected back to our eyes, making the object appear red.
