- Diazo C film produces a blue dye when developed, providing high visual the contrast on a reader.
- Diazo D film uses yellow and blue dyes to create a black image when developed. These dyes peak in absorption at about 470 and 580 nm, respectively. The blue dye gives visual contrast and the yellow dye controls the contrast of next-generation prints onto this product or other blue-sensitive materials.
