Golden Ratio Relationships in Color

Phi relationships in a color spectrum produce rich, appealing color combinations

Michael Semprevivo has introduced a concept called the PhiBar, which applies phi relationships to frequencies, or wavelengths, in the spectrum of visible colors in light.  Colors in the spectrum that are related by distances based on phi or the golden section produce very rich and visually appealing combinations.

This is illustrated below on the screen shot of his PhiBar program.  You can experiment with the PhiBar program, written in Visual Basic.

The PhiBar produces color combinations of the Tabernacle as described in the Bible

Using the PhiBar program above, J.D. Ahmanson discovered that it produces the colors that the Bible says God gave to Moses for the construction of the Tabernacle.  As it says in Exodus 26:1, “Make the tabernacle with ten curtains of finely twisted linen and blue, purple and scarlet yarn, with cherubim worked into them by a skilled craftsman.”  This reference to the combination blue, purple and scarlet in the construction of the tabernacle appears 26 times in Exodus 25 through 39, describing the colors to be used in the curtains, waistbands, breastpieces, sashes and garments.

Set the primary color of the PhiBar to blue, the secondary color of the PhiBar to purple and the Phi color is scarlet, as illustrated below:

The blue, purple and scarlet colors in the Tabernacle of the Israelites are based on phi or golden ratio relationships in color, as shown by PhiBar software

PhiMatrix software produces a rich color palette based on the Golden Ratio relationships of two colors

A more extensive color palette generator in included in PhiMatrix software, which produces a broad range of colors based on golden ratio relationships between two user selected colors and selected HSV saturation and HSV value options:

    “Energize” – The sound made on Star Trek…I’m going to see if your Phi Bar program can tell me the colors it equates to. And I would love know more of your research re the Tabernacle.

    Wow!! this is very peculiar indeed. I have never thought of that.So Phi is a very important formula in everything that surround us,Well have you studied lightspeed and gravity in relation to this phenomenon? From that understanding,what can we deduce regarding the Biblical number 666? Thanks for enlightening me but can you be more simplified?
