smiths, potters, and glassblowers depended on the color of the glowing material to track progress. Consider what happens when an iron bar is heated to a soaring temperature. First, it glows red, then as the temperature rises, it becomes blue-white. These craftspeople...
Part 2: Color Rendering Index (CRI) is used to measure artificial, white light sources Light sources can be grouped into either artificial or natural light sources. In most situations, we are concerned about the color quality of artificial forms of lighting, such as LED and fluorescent lamps....
What is color temperature? Color temperature is a system that uses numerical values to measure the color characteristics of a light source on a spectrum ranging from warm colors to cool colors. The numerical values are referred to as degrees Kelvin (K). We often associate orange with warm and...
Temperature Color temperature is the warmth or coolness of a color or a combination of tones. Warm colors are generally red, orange, or yellow and they're associated with energy, brightness, and action. Cool colors include blue, green, or purple and they're often identified with calm, peace...
Snowshoe rabbits time the coat change in spring from white to brown based on the change in day length, not the temperature or the presence of snow in their habitat. Nowadays, the snow is melting a week on average before the change in day length signals the change in coat color, leaving ...
Another important aspect is the thermal emittance of white roofing: white roof surfaces emit 100 % of the absorbed heat, helping to maintain a more-stable, cooler temperature inside the building.By emitting un-wanted solar heat gain, a white roof will increase the building's energy efficiency,...
What color temperature is right for me? Understanding Kelvin temperature (K) makes it easier to choose lighting that gives you the look and feel you want. Color Temperature(KELVIN)2700K3000K5000K Light Appearance Warm White Warm White Cool Daylight Ambience Cozy, inviting Warm, welcoming Crisp,...
Black ice is actually almost perfectly clear. It has no trapped air bubbles and no swirls (aka occlusions, if you want to use the proper term for bubbles and swirls trapped inside ice). White ice is, of course, white and translucent (some light gets through) or opaque (no light gets ...
What is the significance of color contrast in color theory? Color contrast is how different two colors look when placed next to each other. This difference can come from different hues (like blue versus orange), or different tones (like dark versus light). For example, black and white have...
