INTERACTIVE CIE DEMONSTRATIONS

Please note: these demos require a JAVA enabled browser. If JAVA is not enabled you can view (or click on) the x y chromaticity diagram (below, left) or the u' v' chromaticity diagram (below right). These are gif files, and each one is about 20 kbytes.

Chromaticity diagrams and conversion

These Java applets allow you to select an approximate colour, using your mouse, and read off its x y and its u'v' coordinates, or, more accurately, to key in either x and y, or u' and v', and read off the conversion into the other system.
