The color lambdoma is constructed by weaving columns of the overtone series (1, 2, 3, 4, ...) with rows of the undertone series (1, 1/2, 1/3, 1/4, ...) to form a string-length lambdoma matrix. Drop-by-drop color mixing yields very similar results. It is possible to view a full-color spectrum including black and white by moving the color sliders. This lambdoma can be adjusted by index to three sizes that harmonize at a fifth, a fourth, and the octave. The geometric diagonal running from the bottom-left to the top-right displays dark to light while the other diagonal remains constant at 1/1 throughout. At some extreme stretch of the index, in the space of a yet undiscovered prime number, there exists still a particle of darkness in light, and equally so (though a universe away), a companion particle of light in darkness.
