The Western Wisdom Teachings tell us that the Desire World is fluid, and composed of everchanging light and color. Yes, in one sense you are right.
Color depends upon vibration, the rapidity of the rate and wavelength.
For instance, in the colors of the spectrum red has a much longer wavelength and a slower rate of vibration than violet, which is at the other end of the solar spectrum, but the colors in the Desire World are not at all the same colors that we see here. Here color is caused by the reflection of the Sun's rays in the atmosphere. There light is a property of matter. One might almost say that from the viewpoint of that world desire stuff is light and light is desire stuff. That is not quite correct, but almost so.
