Andrea Binello, the author of “Web Color Names”, says of her Firefox extension: “It is a simple browser/selector for the 140 standard web color names.”
Your students should be aware that HTML/CSS2 defines only 17 color names as standard[1] – they should use RGB (red – green – blue) values for all the rest! (Use this extension to get those values.
)

Note: “orange” has been added to the original 16 color names in CSS 2.1
