A color solid is the three-dimensional representation of a color space or model and can be thought as an analog of, for example, the one-dimensional color wheel, which depicts the variable of hue (similarity with red, yellow, green, blue, magenta, etc.); or the 2D chromaticity diagram (also known as color triangle), which depicts the variables of hue and spectral purity.
A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.
The plot of the gamut bounded by optimal colors in a color space is called the optimal color solid or Rösch–MacAdam color solid. The reflectance spectrum of a color is the amount of light of each wavelength that it reflects, in proportion to a given maximum, which is total reflection of light of that wavelength, and has the value of 1 (100%).
A color wheel or color circle [1] is an abstract illustrative organization of color hues around a circle, which shows the relationships between primary colors, secondary colors, tertiary colors etc. Some sources use the terms color wheel and color circle interchangeably; [ 2 ] [ 3 ] however, one term or the other may be more prevalent in ...
Colors in the NCS are defined by three values, expressed in percentages, specifying the degree of blackness (s, = relative visual similarity to the black elementary color), chromaticness (c, = relative visual similarity to the "strongest", most saturated, color in that hue triangle), and hue (Φ, = relative similarity to one or two of the ...
In a solid, constituent particles (ions, atoms, or molecules) are closely packed together. The forces between particles are so strong that the particles cannot move freely but can only vibrate. As a result, a solid has a stable, definite shape, and a definite volume. Solids can only change their shape by an outside force, as when broken or cut.
