mydomain/pink--x.cfm?page=1

using following rules:

rewriteengine on rewritecond %{query_string} ^(color=.*&page=*)?$ rewriterule ^shop/(.*)--(.*)?page=(.*)/?$  shop/$2.cfm?color=$1&page=$3 [r,nc,l]

but gives me pink--x.cfm not error? there wrong rewrite rule? in advance

if need rewrite url: mydomain/x.cfm?color=pink&page=1 url: mydomain/pink--x.cfm?page=1 rule should be

rewriteengine on rewritebase / rewritecond %{query_string} ^color=(.*)&page=(.*)$ [nc] rewriterule ^([^/.]+)\.cfm$  /%1--$1.cfm?page=%2 [r,nc,l]
