Mood Indigo | Equivalent Approximation Between blue violet |

at snow covering the frozen surface of Kern Lake added a new twist to the evening star trails. The glow on the horizon is from Whiteman Air Force base. This image puts me into a mood indigo, all tangled up in blue/violet. Indigo was one of the seven colors which Sir Isaac Newton defined as a spectral color when he divided up the continuum of visible electromagnetic wavelengths. But he used seven to correspond to other established lists, like the number of known planets, the days of the week, and the musical notes of major scale. It turns out, however, that the human eye is relatively insensitive to hue changes in the wavelengths between blue (420nm) and violet (450nm), so modern color scientists do not distinguish indigo as a distinct division.
“New Age artists and philosophers accept indigo as a spectrum color because it is used to represent one of the seven chakras (the sixth or ajna chakra) of the subtle body.” - David V. Tansley
