JUST ONE PROBLEM: When forming the main (2nd) chart, the script refuses (in my Netscape 4 only!) to recognise that its work is done until +20 SECS LATER! It works fine in Netscape 2+3, and MS-IE2... But you may press "STOP" on your browser early if you get the same problem in N4, to see the chart appear more quickly (with a program-dump underneath - an extra for those interested in Javascript).

Above are the basic 16 colours used by the Windows Operating System (set out as B+W+greys, +primaries [RGB], +secondaries [YMC]). All browsers recognise the 16 names shown, but these are the only colours "quoteable" without confusion. The rest need hex-codes for portability.

Modern video-cards/monitors enable 16-million varieties of color, but browsers still only use about 240-max-colour palettes. These can be 240 varieties of reds, or blues+creams or whatever, to a limit of 240 max. colours in any one image. But that allows all the variety you'll ever really need, as can be seen from the shade-chart of 195 colours below.

The shade-chart itself was programmed from scratch by me to show both a balanced variety of colours and the hexadecimal RGB coding of each colour. The dump-function was modified from an example about arrays in a reference book.
