Since the tripping subject got refreshed and one of our blind members came back to the forum, I've been thinking more and more about colours we see or take for granted.
At 52 I now find I'm needing glasses for reading small print and fine work detail. Am I also experiencing a change in the colours I perceive? If like reading, it happens over a long period of time, I can't say that I've noticed.
What I have noticed in the last 15 years or so is we tend to be bombarded with so many amazing colours and shades. Almost like the computer and photography have a new colour palette.
This brings me on to true colours and false colours. Primary colour spectrum, Black & White.
i have been looking at images from the many telescopes pointing out into the solar system and behond. Some of the images that I think have been interpreted by man and computer, just blow my mind.
So it's got me thinking about colours in the natural world. From the beginning of our planet to present day. Are we creating more and more colours or have we exhausted the digital and chemical range?
When our planet first formed. Rock and molten rock would have a limited range of colour and shades. But would have been primarily the total extent of the colours and shades on earth. Other planets and stars may have been visible as light.
Then came water, so blues, then phytoplankton released oxygen and algae along with photosynthesis in simple plants would provide green.
Life in water would have need to use colour for identification, both for breeding, camouflage & food source identification. So I can imaging the spectrum started to develop at this point utilising sunlight.
As animals and birds developed agian for similar reasons to aquatic life colours would play a roll and eyes would develop in evolutionary terms to make further use of light and colours.
Once the flora and fauna became established, it would be evolution within these species that created any new colours and shades until man came along. Early artists finding pigments to turn into paint. Then the electronic era and electromagnetic spectrum.
What we see in the natural world is only from the light colour spectrum and what is or isn't absorbed and reflected back into our eyes.
i have a question's Is green the only light I can see when looking at the suns light through a leaf? If so does that mean the leaf is blocking all other colours in the light spectrum from penetrating and coming out the other side of the leaf? Is the leaf absorbing other coulours from its surface on the light side?
My other question is, can we continue to make completely new colours or shades with the technology we have today? Or are there new ways to make our eyes intercept, detect colours our eyes have not evolved to do so?
Black is black because it doesn't absorb or reflect light?
