Blue Regal

Blue

Blue is one of the three primary colours in the RGB (additive) colour model, as well as in the RYB colour model. It lies between violet and cyan on the spectrum of visible light. The term blue generally describes colours perceived by humans observing light with a dominant wavelength between approximately 450 and 495 nanometres. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called the Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective.

Noun

1. A small, portable organ whose sound is produced by brass beating reeds without amplifying resonators. Its tone is keen and rich in harmonics. The regal was common in the 16th and 17th centuries, and has been revived for the performance of music from those times.
2. An organ stop of the reed family, furnished with a normal beating reed, but whose resonator is a fraction of its natural length. In the 16th and 17th centuries these stops took a multitude of forms. Today only one survives that is of universal currency, the so-called vox humana.
