RED - BLUE - GREEN

The three most powerfull colours in the universe the primary colours of splitted light.

This poll is about the symbolisme of each of these colours.

RED is the colour for the Flash, for Netflix, it tells cars to stop, it is the colour of garbage for unresycled general waste. The colour of anger, love, ire and passion
Red is the colour of socialist politics and Red is the colour of culture.

BLUE is the colour for Superman, the colour of (no apps i use actualy), it is the colour of sirens. The colour for hope, wisdom, freedom and strange. It is the colour for the earth, for plastic resyceling. It is the colour fof conservative politics and the colour for structure.

GREEN is the colour for Green Lantern, for Spotify, it is the colour for cars to drive. The colour for will, envy, genesis and fruitfullness. The colour for food waste resyceling. It is the colour for ecology and enviromental politics and the colour for nature.

......Everton....... I've been stuck with Royal Blue since the 60s..... For my sins! Some great rock songs with Red in the title, though!

Putting my Physics teacher's hat on, Red, Blue and Green are indeed the primary colours of light. Our eyes (the cones in the retina) detect these wavelengths of the visible spectrum and the brain produces all the other colours from these three - based on their intensity/sensitivity. Light reflected or emitted from surfaces (essentially material-based, such as the concept of paints and pigments) - do not work on light addition (where all three colours produce white light), but subtraction (these three colours in pigment produce black = no light emitted). In this case the primary colours are yellow, cyan and magenta (as our printer cartridges testify too).

... of course, all emitted light are made of photons of wavelength/frequency corresponding to energy level transitions as excited electrons de-excite, based on E = hf, where..........😴😴😴😴😴😴😴💤💤💤💤💤💤💤💤💤 (continued page 69)

was it Newton or Goethe whom paved lost of what we understand regarding the sense, describtion and science behind colours, Newton did so with hes prisme experimeng and Goethe wrote a book on teaching about colours

Newton and GoetheEdit

"The essential difference between Goethe’s theory of colour and the theory which has prevailed in science (despite all modifications) since Newton’s day, lies in this: While the theory of Newton and his successors was based on excluding the colour-seeing faculty of the eye, Goethe founded his theory on the eye’s experience of colour."[28]

"The renouncing of life and immediacy, which was the premise for the progress of natural science since Newton, formed the real basis for the bitter struggle which Goethe waged against the physical optics of Newton. It would be superficial to dismiss this struggle as unimportant: there is much significance in one of the most outstanding men directing all his efforts to fighting against the development of Newtonian optics." (Werner Heisenberg, during a speech celebrating Goethe's birthday)[29]

Due to their different approaches to a common subject, many misunderstandings have arisen between Newton's mathematical understanding of optics, and Goethe's experiential approach.[30]

Because Newton understands white light to be composed of individual colours, and Goethe sees colour arising from the interaction of light and dark, they come to different conclusions on the question: is the optical spectrum a primary or a compound phenomenon?

For Newton, the prism is immaterial to the existence of colour, as all the colours already exist in white light, and the prism merely fans them out according to their refrangibility. Goethe sought to show that, as a turbid medium, the prism was an integral factor in the arising of colour.

Whereas Newton narrowed the beam of light in order to isolate the phenomenon, Goethe observed that with a wider aperture, there was no spectrum. He saw only reddish-yellow edges and blue-cyan edges with white between them, and the spectrum arose only where these edges came close enough to overlap. For him, the spectrum could be explained by the simpler phenomena of colour arising from the interaction of light and dark edges.

Woody Allen made an important contribution to the theory of light, though....."Photons have mass? I didn't know they were Catholic!"

Hi,
