Cyanines, also referred to as tetramethylindo (di)-carbocyanines[1] are a synthetic dye family belonging to the polymethine group. Although the name derives etymologically from terms for shades of blue, the cyanine family covers the electromagnetic spectrum from near IR to UV. Chemically, cyanines are a conjugated system between two nitrogen ...
The dye is an organic compound of bromine (i.e., an organobromine compound), a class of compounds often found in algae and in some other sea life, but much more rarely found in the biology of land animals. This dye is in contrast to the imitation purple that was commonly produced using cheaper materials than the dyes from the sea snail. [2]
Cyan (/ ˈ s aɪ. ə n,-æ n /) [1] [2] [3] is the color between blue and green on the visible spectrum of light. [4] [5] It is evoked by light with a predominant wavelength between 500 and 520 nm, between the wavelengths of green and blue.
Red, green and blue lights, representing the three basic additive primary colors of the RGB color system, red, green, and blue. Pure yellow light is composed of equal amount of red and green light. The color box at right shows the most intense yellow representable in 8-bit RGB color model; yellow is a secondary color in an additive RGB space.

The dyes used in the process are very spectrally pure compared to normal coupler-induced photographic dyes, with the exception of the Kodak cyan. The dyes have excellent light and dark fastness. The dye transfer process possesses a larger color gamut and tonal scale than any other process, including inkjet.
