If you have questions about colour, you can always use one of our e-mail addresses to ask, but some of your questions will be certainly forwarded to our foreign advisers, who are high profile colour scientists. One of them is Stephen Westland. He has a very interesting colour-chat blog where you can ask him colour-science related questions. Various aspects of colour science are covered on his blog, such as culture, design, fun, technology. And there are many answered questions you might not even have thought about, like for example: Why do we value gold? Is indigo a colour of the rainbow (you will be surprised to find the answer)? What are the dangers of Likert scale data? Did you know that people with brown eyes are considered to be more trustworthy? Did you ever hear about tetrachromats?
Accurate documentation and tools in the field of Colour Science are hard to find and expensive to buy, but Bruce Lindbloom has compiled an excellent website full of information, calculators, and examples. Although the material presented on his website is hard to understand without basic knowledge of colour, it is probably the best place to visit for anyone involved in Colour Science or who is just interested in this field.
Modern day colour theory and mathematical color system is based on Munsell’s theory of color. Albert H. Munsell, who was an artist, not a scientist, laid the foundation for today’s computerized color matching systems and enabled a greater understanding of color principles. He developed his color theory to bring clarity to color communication by establishing an orderly system for accurately identifying every color that exists. The Munsell colour system has gained international acceptance and has served as the foundation for many colour order systems, including CIELAB. The colorimetric coordinates of the colours have been published, so the colours are not proprietary. The Munsell Color Company, founded by A. H. Munsell, including the Munsell Book of Color, are owned now by X-Rite, Inc.
The Natural Color System (NCS) is a proprietary perceptual color model, which is based on the colour opponency description of colour vision. The system is usually used for matching colors rather than mixing. NCS is the reference norm for colour designation in Sweden, Norway and Spain and is also one of the standards used by the International Colour Authority. Traditional Thai Colour Names have been matched in part with NCS, having a special license from NCS Color AB.
Colour order systems in arts and science are very well described at colorsystem.com, starting with Pythagoras, Aristotle and Plato. The link on the right points at the ISCC–NBS System of Color Designation which is a system that initially consisted of a set of blocks within the color space defined by the Munsell color system as embodied by the Munsell Book of Color. Over time, the system’s boundaries were tweaked and its relation to various other color standards were defined, including for instance those for plastics, building materials, botany, paint, and soil. ISCC stands for "Inter-Society Color Council" and NBS for "National Bureau of Standards". The system tries to create a colour designation that is sufficiently standardized to be acceptable and usable by science, sufficiently broad to be used by science, art, and industry, and sufficiently common to be generally understood by the public.

Colour Science for Painters. Although the title is very sugestive, we will describe the website briefly using the author's own words. "This website is devoted to applying colour science to everyday problems that painters face. The goal is to provide, as far as possible, a rigorous understanding of the use of colour in painting. Although justifications for the results can be highly technical, the results are presented non-technically wherever possible, with an eye to practical employment by artists." Most links on the website's mainpage are downloadable pdf files. The rest of the website, accessible through a menu unconventionally placed at the bottom, offers a wide range of open-source Octave/MATLAB routines that perform computations involving the Munsell colour system and the Kubelka-Munk mixture model, grouped in "The Munsell and Kubelka-Munk Toolbox" and also many Munsell Resources as well as a list of Colour Science Papers.
The International Colour Association publishes on its website the latest news about colour. In their newsletter section can be found annual reports of latest events related to colour in many countries. The Journal of the International Colour Association is an on-line, free-access, peer-reviewed journal devoted to all aspects of colour that can be accessed from the menu of the website. Along with other useful informations, there is also a "link" section on this website that lists the web addresses of other related associations, of other colour journals and of other colour organizations.
