True Color Challenge

I am not one colour, I am iridescent, I am them all.

I do not belong on a chart, I am off the spectrum, I am travelling on a whole new light wave.

I am transparent enough to allow others to shine through. I am opaquely evocative . I am solid enough to be relied upon.

I am a new colour. Neither dark, nor light, but every shade in between. I am hot, cool, tranquil and intense.

I am one, but we are many.

How would you describe yourself?
