Adnan Baradi has possibly fallen into a simple trap and I wonder if he has
fully tested his scheme using bogus data. I would also respectfully ask 
him whether he is fully conversant with hexadecimal numbers.

The two leading browsers, Netscape and Explorer, and possibly Opera too
although I have 
not tested it, will attempt to interpret the string 'COLOR="#xxxxxx"
regardless of how many 
characters are in the string or whether they are legal. I recall that a
null string, is also parsed. 

The browsers do not appear to report an error or crash if they encounter an
illegal colour string. 
There does not appear to be any initialisation of the memory locations in
which the RGB colour 
integers are stored and illegal strings simply generate random colours.

You can find a little more about this on my web-site at
http://www.nationalfinder.com/html/colrbugs.htm
where I give examples of colours derived from words about bicycles, fruit
and vegetables.

Kind regards,

Roger Harris.
