How can I redirect URL with get parameters

Hi!

1. I want to make an redirect from url like:

localhost/xxx/page.php?value=somestring

to

localhost/xxx/page/somestring

I already made it with that:

RewriteEngine On 
RewriteRule ^color/([^/]*)$ /xxx/page.php?value=$1 [L]

But there is one thing. It would not redirect me to

localhost/xxx/page/somestring

when I manually write old url with parameters, like this:

localhost/xxx/page.php?value=somestring

.

How can I do that?

2. The second thing is that, my parameter sometimes could begin with # sign, which is converted to %23. How can I cut that "%23%" from the beggining? Want to do more friendly URL for SEO, you know. And redirect it too, like in first question.

What I have tried:

RewriteEngine On 
RewriteRule ^color/([^/]*)$ /xxx/page.php?value=$1 [L]

As i wrote, it works, but not redirecting.
