RED Colourspaces Derivation

Introduction

The purpose of this document is to illustrate the steps we followed to compute RED colourspaces primaries.

The most important attribute used to specify an RGB colourspace is the set of 3 chromaticities or primaries encompassing the gamut of colours that the RGB colourspace can represent.

A convenient way to view an RGB colourspace gamut is to project it onto a chromaticity diagram such as the CIE 1931 Chromaticity Diagram where the primaries define the triangle encompassing the gamut.
