Every time we see and look at a rainbow in the sky, each of us has radiant smiles on our face as the effect of joy reflected from Inside our happy mind. Do you know how many colors are there in the rainbow?

Furthermore, our Khmer ancestors seemed clearsighted to adapt our national traditions to wear silk costumes a color for each special ceremonial day (of the week) of the seven colors -- almost similar to those of a rainbow we call "Arch of Indra."

There are seven colors in the light as evidenced by rainbows which are the effect of sunlight spectrum on vapour hung in the air.

We can prove by just using a prism or more simply a transparent bic/pen held in direct light to reflect it on a surface in the shade.

You'll see artificial rainbows with the same seven colors of those in the sky in order as follows:

Red (main)
Orange
Yellow (main)
Green
Blue (main)
Indigo and
Violet

The three main colors are Red, Blue and Yellow. The others are obtained from mixing the three or the three with the White, etc. If you want to have a pale color you have to put the White of greater amount than other colors.

Red + Yellow > Orange
Red + Red + Yellow > Dark Orange
Red + Yellow + Yellow > Pale Orange ...
Yellow + Blue > Green
Red + Blue > Indigo or Violet (according to amount used)
...
Do you know how to make white color? if you mix all the seven colors each of equal amount and stir it thoroughly, you might be surprised to see the White.

Red + White > Pink
Red + White + White > Pale Pink
Green + White > Pale Green
Blue + White > > > Pale Blue > > > Sky Blue ...
...
Red + Black > Dark Red
Blue + Black > Dark Blue
...
Black + White + White ... > Gray/Grey
