A LAMBDOMA GRID FORMED BY TWO INTERSECTING ELLIPTICALS.

THE BEGINNING TONE in this case is G (blue). On the overtone side the progression is from blue to purple, while on the undertone side the progression is from blue to yellow (top left).
At right angles to the diagonal G (blue) just mentioned, to the right the overtone extends from blue to purple to blue to green to yellow to orange and to red, with the spaces between the diamond shaped tones being purple between the blues, blue red and yellow red between the blue and the lavender, yellow orange and yellow green between the purple and the blue.
Always the colors separate to their adjacent tonalities, horizontally and to their polarities within the same color vertically.
On the left the same process occurs but is reversed entirely. The sequence is from blue to green to yellow to orange to red to purple to blue, with the background colors also changing top to bottom within the same tonal family.
The bottom group clearly shows the right left complementary pairs, blue on the left and red on the right.
The significance of the color combinations is that they are linked directly to the assigned tones based on fifths in music and laid out on an extended Lambdoma grid of fractions used as ratios in music.
