How many colours is white light made up of ?

Answer 1

Answer 2

Answer 3

When light is refracted through glass it splits into the same colours that you see in a rainbow.

Red / Orange / Yellow / Green / Blue / Indigo / Violet
Remember it this way based on the first letters of the colours :

Mr. ROY. G. BIV loves to wear all the colours of the rainbow.

Answer 4

it is made of all colours. If you put the colours of the rainbow onto a circular disc and spin it, it turns white. An easy way to remember the colours of the rainbow and in the right order is:-

Richard/red
Of/orange
York/yellow
Give/green
Battle/blue
In/indigo
Vain/violet

good luck

Answer 5

Yellow (red plus green) is the complement of blue because when the two colors are added together white light is produced

Answer 6

The spectral primaries are pure colors and deal with light sources. The light impinging on an object is, for example, red. No matter what "color" the object might appear when illuminated with white light it will appear red when the light source is pure red (assuming at least some of the light is reflected instead of absorbed). In are you very rarely have light of a pure color. Instead, an object appears red because it absorbs all colors except red. The red light is reflected to our eyes. This difference is why when you mix red, green, and blue light sources you perceive white light but if you mix red green and blue colors you get black. The red color absorbs green and blue, green absorbs red and blue and blue absorbs red and green. The net result is all colors of light get absorbed and you perceive black. Media that combine emitted lights to create the sensation of a range of colors are using the additive color system. Television is the most common use of this. The additive primaries are red, green, and blue. Because of the response curves of the three different color receptors in the human eye, these colors are optimal in the sense that the largest range of colors — a gamut — visible by humans can be generated by mixing light of these colors. Additive mixing of red and green light, produce shades of yellow or orange. Mixing green and blue produces shades of cyan, and mixing red and blue produces shades of purple and magenta. Mixing equal proportions of the additive primaries results in shades of grey; when all three colors are fully saturated, the result is white. The color space that is generated is called the RGB ("red, green, blue") color space.
