"True Color" vs. what other kind of color?

[loreilly]

Ra mentions a 'true-color' has metaphysical properties to it and Don even gave us a hexadecimal value pertaining to true-color green that Ra confirmed was closest but lacked metaphysical properties.

This would be the closest quotes I can find?

33.4 Questioner: I would think that you could achieve a true color by passing the light through a crystal of the particular color. Is this correct?

Ra: I am Ra. This would be one way of approaching accuracy in color. It is a matter of what you would call quality control that the celluloid used is of a varying color. This is not a great or even visible variation, however, it does make some difference given specific applications.

33.5 Questioner: Possibly the use of a prism breaking white light into its spectrum and then screening off all parts of the spectrum except that which you wish to pass through a slit and use would be even better. Would this be true?

Ra: I am Ra. This is correct.

Ra: I am Ra. (...) However, the frequency that is the basis of each density is what may be called a true color. This term is impossible to define given your system of sensibilities and scientific measurements, for color has vibratory characteristics both in space/time and in time/space. The true color is then overlaid and tinged by the rainbow of the various vibratory levels within that density and the attraction vibrations of the next true color density.

Thanks Nia.... that last quote is intriguing in that it seems to be saying that understanding what the "true" part is may not be possible.
