As the co-chair of the IES Color Committee I am delighted (pun intended) to announce the publication of the Design Guide for Color and Illumination<\/em><\/a>. \u00a0The guide is the result of over five years of work by more than a dozen researchers, engineers, manufacturers, and designers from across the globe. \u00a0Here’s part of the description on the IES site.<\/p>\n

Color can be described using concrete values such as chromaticity coordinates, spectral power distribution, or others discussed later in this guide. However, one\u2019s response to color can be much more personal and emotional\u2014and therefore more difficult to quantify. This guide takes the reader from basic vision and color vocabulary, through methods of measuring and quantifying color, and culminates in the practical use of commercially available white light and colored lights. The definitions, metrics, and references discussed will assist in building a critical understanding of the use and application of color in lighting.<\/p><\/blockquote>\n

It is probably the best, most thorough discussion of light and color available today. \u00a0Everyone interested in color, color perception, color rendering, and their relationship to light should read it. \u00a0It will be available at the IES booth at Lightfair<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
