If the beam of light is not orthogonal (or rather normal) to the boundary, the change in wavelength results in a change in the direction of the beam. This change of direction is known as refraction. The refractive quality of lenses is frequently used to manipulate light in order to change the apparent size of images.
This can only be used as a very rough guide, for instance if a narrow range of wavelengths within the band 647–700 nm is absorbed, then the blue and green receptors will be fully stimulated, making cyan, and the red receptor will be partially stimulated, diluting the cyan to a greyish hue.

Cherokee spiritual beliefs are held in common among the Cherokee people – Native American peoples who are Indigenous to the Southeastern Woodlands, and today live primarily in communities in North Carolina (the Eastern Band of Cherokee Indians), and Oklahoma (the Cherokee Nation and United Keetowah Band of Cherokee Indians). Some of the ...
The sales volume of a company whose product is defined by the name of its color is susceptible to the symbolism and association of that name — in one example, a company selling a paint color named "off white" more than doubled its sales simply by renaming the same color "ancient silk".
Colour names often developed individually in natural languages, typically beginning with black and white (or dark and light), and then adding red, and only much later – usually as the last main category of colour accepted in a language – adding the colour blue, probably when blue pigments could be manufactured reliably in the culture using ...
The Roman emperor was the ruler and monarchical head of state of the Roman Empire, starting with the granting of the title augustus to Octavian in 27 BC. [2] The term "emperor" is a modern convention, and did not exist as such during the Empire.
