Another day of research

Today I've been working with this book which is by the same author as th brown and orange on in the previous post.
It's a bit more of an overview but includes some interesting information on colour in general, example: It was Newton who decided on the 7 colour rainbow (red, orange, yellow, green, blue, indigo, violet) and this was because of the 7 notes of the musical scale. This is interesting because when you look at a rainbow it is easy to put the colours into those 7 compartments, but I suppose this is because we have all grown up learning these to be THE colours. When in reality (and once you actually start describing colours you see) the colours blend seamlessly into each other, it is interesting that we don't have that many words for in-between colours... the only one i can really think of which is used in common language is turquoise... for example what do you call the colour between orange and yellow? (we would probably just say yellowy-orange) It's also strange that Newton chose to define indigo as a specific colour in between blue and purple (violet).
This isn't really relevant to my research but I found it interesting.
On a more relevant note:
There is a quote from H W Bronsin and E O Fromm which says: (a colour blind person) "may lack the phenomenal color experience from the physical stimulus, but there seems to be no reason to doubt that he experiences the same physiological effects."
Which I think is a critical point. I had wondered whether the effects of colour depended on a person being "chromatically aware" or whether the effects are sub-conscious. However, if this statement is correct then it means that colour can be used effectively perhaps even on unconscious people (coma patients?)
Since certain wave lengths of electromagnetic waves have effects on us - infra red, ultraviolet, x rays etc... then it is not inconceivable that waves within the visual spectrum also affect us past the purely visual reception.
I also read about cases where many high caste Hindu women and children in India developed rickets because they were kept inside as this was seen appropriate for their caste, and the lack of sunlight meant that their bodies did not produce enough vitamin D.
I learnt the word "Photobiology" which I think is a useful (if imaginary) word.
I also made a diagram to outline the activities that take place in a health care environment, so that I know what I'm dealing with.
