Poetry

Red is the colour of blood that flows in the body of all creatures given birth
Green is the colour of grass that like a carpet covers a lot of the soil of earth
Blue is the colour of sky that surrounds this world and is of an infinite girth
All three colours come from a Single Source having an Immeasurable worth.

Red is also the colour of danger and a symbol which indicates all to beware
Green is also the colour of the leaves that most of the plants and trees wear
Blue is also the colour of water that covers most of this world which is fair
Three colours are the original blend of all those others found in nature there.

Red is also the colour of anger, passion or pain that is expressed, felt and seen
Green is also the colour of something natural an indication of where it has been
Blue is also the colour of Infinity and the light glowing in a mind which is clean
And all three colours are shades of One Light the essence of all universal sheen.

Of all the three colours I like blue the most as it seems to be uniquely sublime
It speaks to me of loftier and deeper things that were experienced in my prime
It also represents the colour of the biggest phenomena known to man in time
Being a symbol of That in which all exists and from which all began to chime.

Note: 
There are many other colors but as far as those which form the basis of technology there are only three i.e; as in a R.G.B. monitor and screen projector etc.
