Answer 1

The usual error for this is leaving out the NameVirtualHost directive if you're still using httpd 2.2
Add the following in your config file and it'll probably work
NameVirtualHost *.80
You might want to read the documentation for Named-based Virtual Host Support with httpd 2.2.

Answer 2

NameVirtualHost *.80
<VirtualHost localhost:80>
ServerName color
ServerAlias localhost
ServerPath "C:/wamp/www/subwww/color"
DocumentRoot "C:/wamp/www"
<Directory "C:/wamp/www/subwww/color">
Options Indexes FollowSymLinks
AllowOverride All
</Directory>
</VirtualHost>
in above code, subdomain name is color
and the url is http://color.localhost/
if the operating system is windows then add "127.0.0.1 color.localhost" in "C:/windows/system32/dirvers/etc/hosts" with notepad run as administration
