Color motion picture film any kind, particularly including monopack color motion picture films in 65/70mm, 35mm, 16mm and 8mm. The "Monopack Agreement" had no effect on color still films. Monopack color films are based on the subtractive color system, which filters colors from white light by using superimposed cyan, magenta and yellow dye images. Those images are created from records of the amounts of red, green and blue light present at each point of the image formed by the camera lens. A subtractive primary color (cyan, magenta, yellow) is what remains when one of the additive primary colors (red, green, blue) has been removed
Shades of magenta a single wavelength. Humans, being trichromats, can only see as far as 380 nanometers into the spectrum, i.e., as far as violet. The hue magenta is the complement of green: magenta pigments absorb green light, thus magenta and green are opposite colors. Before "printer's magenta" was invented in the 1890s for CMYK printing, and "electric magenta" was invented in the 1980s for computer displays, these two artificially engineered colors were preceded by the color displayed at right, which is the color originally called "magenta" made from coal tar dyes in the year 1859. Besides being called original magenta, magenta dye
