Human Rights & Equity OfficeBriefly explained, colours on a computer screen are displayed combining red, green and blue light sources, each within a range of 0 to 255, allowing for a possible 16 million colours. Most modern monitors are capable of displaying this full-range of possible colours (i.e. 32-bit). However, a web-based delivery cannot ensure the same level of colour accuracy that, for example, using Pantone control numbers might provide in the print medium. The best one can hope for on the web is a consistent user experience from one page to the next, as the same web page viewed in two different monitors, or on different operating systems, may look very different.
As part of , ¾ÅÐãÖ±²¥ Department of Marketing and Communications has developed an approved list of institutional colours (red, gold, and blue) for the web that should be referenced as an appropriate starting point in developing a design palette for any ¾ÅÐãÖ±²¥ web development projects.
Finally since color is deemed a "presentational" value (as opposed to a semantic value), its use is governed by Cascading Style Sheets.
