All the colours of the Rainbow

What are the colours of the Rainbow....?

Red
Orange
Yellow
Green
Blue
Indigo
Violet

The fact that there are seven seems significant to me, since it is the number that God uses to represent completeness.

However, I don't know why what we know as "purple" on the normal colour wheel would have been split to give indigo and violet.

I like the fact that when we talk about the entire spectrum we will refer to the colours as "All the colours of the rainbow". Even with technology we can try to reproduce the entire spectrum, but it is amazing that our eyes can identify changes in colour without any technological aids.

Looking at the colour wheel, we are taught that there are three primary and three secondary colours. we can split them up further to lessen the stark changes. Furthermore we can add black to each and get all the shades and then also add white to get all the tints, to produce a wheel similar to the picture.

Add a little more black or a little more white, and you have a different colour altogether. That is why one has to be so careful about dyelots when ordering fabric for production. One cannot mix dyelots within garments, because it will be noticed, especially under neon light or sunlight, and after washing the garment a few times it will start to show.

Unlike the fading of fabric, the promise behind the rainbow, to never destroy the earth again by flood will not ever fade away. (Genesis 9:12-16)

I started the blog with black and white and then went on to scarlet and violet (purple) in another post, which you can read by clicking on the relevant link in the list above. In the future I will look at each of the colours, just keep on reading.

Ok, Yellow and Orange have been added, follow the link above.
EDIT Green and blue are up - one remaining
