My Traffic light

Earlier in the week I was thinking about what a traffic light would look like if I had designed it. If I designed a traffic light it would be an equilateral square shape. The leading edges of the traffic light would have a frame around it that was black and white striped.

The squared traffic light would be split down the middle. On the left site would be a grid like panel filled with dots to make written information like the time and temperature and traffic conditions further down the road. Or to make signs about the junction like no right turn. The grid of dots would be light emitting diodes and have a resolution similar to 90s Tamagotchis. The left screen would also show a count down timer for when the light would change.

The right hand side would be the signal. Four rectangular coloured signals would be used, Red to stop yellow to prepare to stop or wait. Green to go and blue when the light is not active as a traffic light.

Blind and colour

It turns out I'm not the only guy in the world that questions reality.

Jim Carrey seems to be onto something and David Icke  is convinced we are living in a distorted world that is controlled by Reptile like humanoid beings.

I watch David Icke's videos from time to time. I don't agree with everything he says but his conferences are very interesting. I remember once he said that we can't see most frequencies of light, I think this is very true. I put our blindness down to the size of the cone and rod cells in our retinas, they are only about 500 micrometers across. The cells must be able to touch both sides of a light wave to detect it, so this means that only light waves that are close to the 500 micrometer diameter of the cells can be detected by them. Well. Infra red light waves are still very narrow but they are much bigger than the cells so they can't be seen. Ultra violet light waves are smaller but they can't pass through the lense of your eyes. With radio waves, forget it. They go from 1 mm to thousands of kilometers.

This leaves me with one big question. If we could see all the wave lengths of light, would our brains assign colours to them? Are there more colours beyond the red and violet that no person has seen? ( I spell colour the English way).

Also

Do our brains all assign the same colours to the different frequencies of light. Is my reds someone else's green? How would you describe the colours that you see?
