A colourful sonnet

Am I able to explain what you lack,
when all you can perceive is total black?
Missing a world with multiples of hue,
never a look at skies of clearest blue.

Am I capable to set you the scene,
of fields stretching away, full of green;
and how many countless a tear is shed
upon receiving those roses of red.

But, we are only just a mere human,
as no-one can really describe cyan.
Let alone that odd magenta fellow
and nothing is just, primary yellow.

Every colour is contained in white,
when you are able to behold the light.
