If you access
www.facebook.com/dell you'll be redirected to the Dell page of your country.
Can I make the same thing with my page?
Like, when you access
www.facebook.com/RedPurpleSecondPage to be redirected to
www.facebook.com/RedPurple without having to click anywhere?
The answer to your question is that this is not possible due to the Facebook.com domain name belonging to Facebook rather than belonging to you.
If you were the owner of the domain name then you would be able to set a redirect.
