Light Color and Color Rendering

True Colors do not exist. People tend to judge colors under what they consider to be natural or true lighting conditions, often  mistakenly using daylight for this purpose. but the colors seen under daylight on a Sunny day can be widely different to those seen on a day with overcast sky. For the spectral distribution of daylight is not constant, but is continually changing from hour to hour and from season to season. The correct thing to do, of course , is to assess the colors under the same type of lighting as that existing in the area where they will be finally seen. For example, an evening dress would be chosen under incandescent lighting, for this is the sort of lighting most likely to be employed at the evening function where it will be worn. Similarly, the color scheme for an office should be preferably be chosen under lighting identical to that which will later be installed there.

Light & Vision

Image
VISION A simple definition of LIGHT is visually perceived radiant energy. This visible light is a small part of the ELECTROMAGNETIC SPECTRUM and ranges in wavelengths from 380 nm to 780 nm. Light is what energizes our visual system. Light reflected from objects  into our eyes enables us to see.Lightwaves enter the human eye and send signals along the optic nerve.Light enters the eye through the pupil, is focused on the retina, and is transmitted to our brain via the optic nerve. A significant part of our brain is dedicated to the processing of visual information. Of all creatures on this earth, the human visual system is the most impressive. Birds may have sharper vision, felines may be more sensitive to motion, and horses may have almost a 360-degree field of view, but nothing can beat the combination of features humans possess. The human eye allows good depth perception, excellent color perception, reasonable motion detection, and great visual acuity. PERCEPTION...
