In viewing a rainbow, one is exposed to the wonders of the colour spectrum revealed to the eye as red, orange, yellow, green, blue, indigo and violet.
May one then ask where white and black feature? White is in fact a reflection of all colours, black on the other hand being the absorption of all colours. Whether having biblical connotations or not, a rainbow is a sight to behold and many other varying velocities of light contain all the splendours of the universe.
Colour becomes apparent due to different frequencies of light from an untold number of objects.
For example, an apple is not coloured red, the frequency of light reflected off the apple reaches the optic nerve in the brain which transmits the ray, the eye then observes red.
In a previous article, colour and it’s affects were discussed, red being vibrant and stimulating, yellow a nerve tonic as is sunlight, green the colour of nature calming, blue suggesting spaciousness, chilly and for some depressing and violet cold and magnetic.
There is no doubt that colour plays a role in our emotions and industry utilizes this to enhance and lure consumers to their products and services.
But what is the origin of these emotions? Well these commence as an inner feeling and how one reacts is up to the individual. We react to many stimuli and the outcome generally depends on the practicality or maturity of an individual.
However, back to the colour spectrum ! Beyond the visible red of the spectrum ` the long, invisible infra-red rays exist, characteristically having properties of deep penetration and for this reason have to be used with caution. The suggested time span is 5 minutes per treatment otherwise there is a potential for deep tissue being burned. Infra-red treatment is commonly used to relieve pain. Beauticians utilize these rays for the penetration of creams and oils when clients suffer from dry skin and scalp.
At the end of the spectrum radiating short rays, the invisible ultra-violet rays occur, having 3 classifications as follows :
UVA rays are the longest, can pass through glass and in relation to skin, penetrate the lower dermal layer causing premature aging.
UVB rays are dangerous in that these affect the lower epidermis can be the cause of skin cancer and thickening of skin.
UVC rays affect mainly the outer epidermal layer, commonly used to treat psoriasis, eczema and acne.
With great awareness of the dangers of sunbathing, ultra violet radiation in a spa or salon will promote a suntan. However clients should enquire of the type of UV rays being emitted with minimal skin damage.
Certain contra-indications exist being exposed to ultra violet rays such as :
Clients with very fair, sensitive skins, those complexions having freckles and/or moles, a history of skin cancer and the intake of certain drugs with photo-sensitivity.
Lastly should clients not have the time or inclination to undergo sun bed radiation, Matsimela has a beautifying topical bronzing crème in store and available online.
