Interactive Colour Demos

 

The following demos have been written in html, javascript and css. They allow you to explore concepts such as hue, chroma and value (lightness), along with some related concepts such as colour difference, by moving some colour chips around on the screen. The demos were written in 2018 by Stephen Westland and Marjan Vazirian.
