A study with ninety-six subjects, ages ranging from 18 to 55, were examined on how a variety of lighting could impact their mood and cognition. Subjects showed higher problem-solving abilities for females in a warm vs. cool white light source. The opposite result was shown for the male subjects. [2]
The color of a light source affects the apparent color of an object the light shines on. For example, the color of an object might appear different in the light from the sun versus from an incandescent (tungsten) light bulb. With the incandescent light bulb, the object might appear more orange or "brownish", and dark colors might look even ...
The CIE 1931 xy chromaticity space, also showing the chromaticities of black-body light sources of various temperatures, and lines of constant correlated color temperature sRGB gamut plotted in xyY color space (chromaticity + luminosity) Chromaticity is an objective specification of the quality of a color regardless of its luminance.
When combined with an LED fixture or colour scroller, the most common features of an automated light can be readily duplicated. [8] "Auto-yokes" are often promoted as a way to modernize and increase the flexibility of an inventory of lighting fixtures at a reduced cost to replacement with intelligent lights.
The RGB color model is an additive color model [1] in which the red, green, and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors , red, green, and blue.
LED art is a form of light art constructed from light-emitting diodes. LEDs (light emitting diodes) are very inexpensive to purchase and have become a new way to make street art. Many artists who use LEDs are guerrilla artists , incorporating LEDs to produce temporary pieces in public places.

For the mixing of colored light, Isaac Newton's color wheel is often used to describe complementary colors, which are colors that cancel each other's hue to produce an achromatic (white, gray or black) light mixture. Newton offered as a conjecture that colors exactly opposite one another on the hue circle cancel out each other's hue; this ...
