The Rainbow Books are a collection of CD format specifications, generally written and published by the companies involved in their development, including Philips, Sony, Matsushita and JVC, among others.
A number of these specifications have been officially adopted by established standards bodies, including the ISO, IEC, and ECMA.
Red Book (1980)
- CD-DA (Digital Audio) â originally published by Philips and Sony on September 19, 1980, it was later standardized as IEC 60908:1987 and later IEC 60908:1999.

Orange Book also introduced the standard for multisession writing.
