Adding all the three primary colors-red, green, and blue-at maximum intensity produces the color , while adding any two of the three primary colors at maximum intensity produces the trio of complementary colors-yellow, magenta, and cyan.

White

Explanation:

Some times when we look at some objects they appear to be different in color to us than their actual color. It may be due to several wavelength of  light with different intensities is striking on our eye.

Remember, white is not a color it is just produced in response to combination of 3 or more than three colors like light.

The three colors that can be combined at full intensity to form a white color are called as primary colors. The most common set is

               Red+Green+Blue= white

Zero intensity of each component gives darkest color and full intensity of any component give a white color.

Secondary colors can be produced by the addition of two colors such as;

                Red+Green=Yellow

                Red+Blue=Magneta

                Green+Blue=Cyan
