The Influence of Tinted Colored Glasses
“To see through Rose-colored glasses” is to have a positive outlook. The veracity of this statement has been tested for years and foregoing. It is quite important to examine the psycho physiological impact of colors on the human brain. Why? Because colors develops visual memory; impels recognition of objects and visual separation due to contrast. The Last statement is acknowledged by cinematographers and photographers dealing with photosensitive materials. When dealing with monochromatic treatment it is quite difficult to separate objects due to the absence of colors. Even the biological Rhythms; Circadian, Diurnal, Ultradian and Infradian are affected by Colors.
The Presence of Blue color affects the Circadian Rhythm due its effect on Melanospin photoreceptors which is most sensitive to color of wavelength about 480 nm .i.e. Blue. Red Signifies Dominance this has been derived from the reddening of skin due to anger. Green hints towards creativity and safety based upon the preferences developed over the years about it. One thing it is the color of which our photoreceptors are most sensitive to Secondly, it was the most prevalent in the world in good olden days hinting a sense of comfort to the eyes. Over the years this response has translated from comfort to safety. The emotional Response to an event can be classified under two categories Affective Valence and arousal. Affective Valence is the emotional response related to pleasure and displeasure. Arousal axis is related to arousal and sleepiness. The Scientific apparatus to measure both these things are HRV (Heart Rate Variability) and SCR (Skin-Conductance Response). All these elements highlight the importance of colors. Further, emphasize the difference between perception and what is being perceived.
A color is perceived when light is reflected by an object. Every object emits light which is termed as Spectrum. Color Filters like Rose-colored glasses can affect this spectrum by reflection and absorption. Gray filters or ND filters reduce the spectrum equally which implies it affects all colors equally while tinted filters are sensitive to specific wavelengths. Tinted glasses are also called Colored Glasses.
Yellow Tinted glasses absorb light with wavelengths below 450 – 500 nm and transmit light above this inclusive interval. It is claimed that yellow – tinted glasses improves reading speed and promptness due to the physiological change of wide pupils. These affects can be a result of diminished contrast caused by the usage of tinted glasses. Several studies are conducted using the IASP (International Affective Picture System) which is a database of images that brings about a specific emotion in the viewer’s psyche. Sample studies are conducted with blocks of images with the percept of pleasant, unpleasant or neutral. The variability could arise from the use of different tinted glasses. The response is generally recorded as a LPP (Late-Positive potential). It is just a slow change, a positive response recorded after 200-300 ms or later after 500 ms generally measured with EEG (Electroencephalography).
The results of several studies on similar lines have observed that Green-tinted glasses are the most pleasure oriented followed by blue, red and yellow. Dislikes are more for Red, yellow, blue and for green it is minimal. While for a neutral perception blue and yellow tinted scored the most. Such studies with larger color gamut’s can be significant for unison of art and science. They could be quite helpful in field of cinema which is a collaborative art form and can incorporate any subject or field of study. So next time when you are going out do not forget to put those color tinted glasses on.
