Most likely you would either get black or brown.
Some of the colors are dark. when you mix colors, you usually end up with something darker,or the same color. so in mixing the colors of a rainbow, it would make a darker, (Icky) colorinstead of getting lighter.===============================Answer #2:-- How are you "mixing colors" ? Are you mixing light, or mixing paint ?Mixing paint is not the same as mixing light.-- There are more than seven colors in the rainbow. Every color that youor anyone else has ever seen is in the rainbow, as well as every color ofpaint ever mixed, every color of fabric ever woven or dyed, every color thatcan be produced on the screen of your computer monitor, every color evernamed, and those without names. All are present in the rainbow.-- The combination of all possible colors of light, in the correct proportions,produces white when they enter your eye and "mix" there.
A secondary color is a color made by mixing two primary colors together.
Mixing all of the colors together makes white light ( if you are talking about light). But if you mix all the opaque colours, i think you get black..
Mixing the light colours of the rainbow will produce white light (i.e. daylight).
The mixing primary colors of pigment is when they are added together, fewer colors of light are reflected and were absorbed, but the mixing primary colors of light is when two of the same amounts of light combined together to form a color of white. If they are not at the same amount of light, then the colors it formed will be the secondary colors.
Brown
Black can be formed by mixing many colors together.
Tertiary Colors
Mixing red and blue colors will make purple color.
depends on what youre mixing.. for example, is it light or paint? all colors of paint together is a filthy brown color.. al the colors of light together is white light.
When you combine all the colors in the rainbow together you get the color black
No colors can make primary colors. There are two sets of primary colors for mixing different kinds of color. For mixing colored lights together, the primary colors are red, green, and blue. For mixing colored pigments or dyes together, the primary colors are magenta, yellow, and cyan (turquoise). Each of these sets of primary colors are the secondary colors of the other mixing system. The primary colors are: red, yellow, and blue. These were the colors the art masters of old used, and are still used today for mixing paint.
