3 primary colours plus what other colour will make all the colours in the colour spectrum?

Answer 1

All the colors can be made from the primaries, red, yellow, and blue. Adding white makes a "tint" (of the same color) and black makes a "shade."

Answer 2

There are two kinds of colour primaries

1. Additive or Light :

Light primary colours are RED, GREEN, BLUE these are the colours that the 3 light receptors (cones) in our eyes respond to. The light from the sun contain all of these colours producing white light. At night no light = black. Therefore all the shades of coloured light are a result of light intensity

Mixing coloured lights
RED + GREEN light = Yellow light
RED + BLUE light = magenta light
BLUE + GREEN light = cyan light (blue green colour)

2. Subtractive or painting primaries

When white light ie from the sun hits the surface of a painted object some of the light will be absorbed by the pigment and the rest reflected back. It's this reflected light that we see with our eyes. Hence the term subtractive, some of the colours in the white light have been removed. If the surface of the object appears white all of the colours are reflected back. If the object appears black the surface has absorbed them all.

Painting Primaries are YELLOW, MAGENTA, CYAN
note magenta is not red but a blue-red cyan is a blue-green

Mixing subtractive Primaries
YELLOW + MAGENTA = RED
MAGENTA + CYAN = BLUE
CYAN + YELLOW = GREEN

CYAN + YELLOW + MAGENTA = BLACK

Because of the characteristics of pigments are not perfect printers add a black ink to cyan, yellow and magenta to make blacks look properly black.

Answer 3

With Magenta, Yellow, Cyan and White you can mix a large part of the spectrum. You can also mix an okay black with these colours (it's not a very dark, true black). If you are painting, you will not be able to mix the spectrum from Red, Yellow and Blue. Your mixed colours (especially violets and greens) will turn out muddy.

Just to clarify, this answer uses the subtractive colour theory. Subtractive colour has to do with mixing inks, paints or dyes (as opposed to additive which deals with mixing light).

Answer 4

there is no fourth colour, red, yellow and blue make all colours in the spectrum. In art the only other colour you should use is white, (black has it's uses for the experinced painter but basically you'd do well to avoid it) In the light spectrum all colours combined make white, the abscence of any of them make black.

A later update:-
Do not add black to darken your colours if your talking about painting, do not have it on your pallet, trust me, it will leave your paintings looking duller and more lifeless. If you want to darken yellow for example mix in tiny quantities of red and blue, learning proper colour mixing is dificult but worth the effort.

I painting you would also use two types of each primary, a cold and a hot. So for example a cold yellow is lemon yellow and a warm is cadium yellow, you need both to be able to mix all colours right.

Answer 5

None the colour theory says there are 3 primary colours red,yellow and blue. These can't be made by mixtures. There are also 2 non colours Black(nothing) and white(everything) all other colours are composites of red yellow and blue

Answer 6

Three primary colors, Red, Yellow, Blue Plus White will make all colors.

Answer 7

Only three primary colours (light) give rise to all the colours of spectrum (visible light). But when one uses paint to create different shades, he has to mix these three colours plus white and black in appropriate proportions.

Answer 8

Depends if you are talking on screen or in print.

Subtractive colours used in printing are Cyan, Magenta and Yellow + Black. You subtract colours to get White or put another way just let the paper showing through.

Additive colour used on TV, Monitors etc. are red, green and blue. You add all the colours to get White, whilst black is the absence of all colours.

Hope it helps

Answer 9

The primaries are yellow, red and blue. You can get all other colors by mixing these together plus white!
There are two color spectrums, though. The material one, which is used in painting, and the light one that photography is based on.

Answer 10

You add white or black to the 3 primary colours to make any colour, hue or tint. Any other colour is made out of the primary colours, and its variables i.e. secondary colours, tertiary colours etc. There is no other single colour you can add. N*ob jockey.
