Colour v black and white

When I think about my vision I am so happy that I can see with the full spectrum of visible light (colour) . I know different animals can only see certain colours, sometimes just black and white and but others like snakes and insects can even see into the infra red and ultra violet.

Then there is colour blindness, where some cells in a person’s eye are not properly developed or can be missing. Then they have colours missing from their vision. For instance red green colour blindness. Apparently males suffer from this more than females. As I say I feel lucky to have good colour vision. X

Fireworks

Sodium nitrate, sulphur and carbon. Mixed together make gun powder. That is the explosive mixture they put into fireworks. The ratios of the different elements determine the burning characteristics. Strontium makes red, sodium yellow, copper green, magnesium bright white, other elements make different colours. Cobalt? Possibly blue. The elements burn at different temperatures. Each element, when heated, excites electrons in its atoms. As they cool down again photons of light are given out (emitted). The colour depends on the energy the photons release. Bear with me it gets complicated! In the same way you can tell what elements are in the sun or other celestial objects by their emission lines. If you look at a spectrum (rainbow of colours), given out by the light of the sun there are gaps, these correspond to gases like Hydrogen and Helium.

I don’t know enough science to explain properly.

Anyway the fireworks have stopped so I might go to bed.

I love colour as you can see.

Colour is the best option for me.

Bright colours are very good.

Not just black and white could

grab my mind…

Without colour I am blind…

I love a spectrum of every hue.

Yellow, red, gold, bronze and blue.

Purple and orange fight to be seen,

Not to mention beautiful green.

So of I will go to paint again.

My palette with new colours, lain.
