Our language has not terms enough to signify the different delicate shades; our factories have not the stuff whose hues might make a chromatic scale for them.
"In this dilemma, we might make a scale of colors from the stars themselves.

We might put at the head of the scale of crimson stars the one known as Hind's, which is four degrees west of Rigel; we might make a scale of orange stars, beginning with Betel as orange red; then we should have Betelgeuze, Aldebaran, ss Ursae Minoris, Altair and _a_ Canis, _a_ Lyrae, the list gradually growing paler and paler, until we come to a Lyrae, which might be the leader of a host of pale yellow stars, gradually fading off into white.
"Most of the stars seen with the naked eye are varieties of red, orange, and yellow.

The reds, when seen with a glass, reach to violet or dark purple.

With a glass, there come out other colors: very decided greens, very delicate blues, browns, grays, and white.

If these colors are almost intangible at best, they are rendered more so by the variations of the atmosphere, of the eye, and of the glass.
