Rainbow Books

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.

This correlates with the fact that CD-R and CD-RW are capable of audio ("Red") and data ("Yellow"); although other colors (other CD standards) that do not mix are capable of being burned onto the physical medium.

The White Book refers to a standard of compact disc that stores pictures and video.

A standard developed by Philips and Sony in the late 1990s, with over 1 GB in capacity and recordable/re-recordable capabilities.
