Christian Mingle does not feature / support interracial couples, nor give the profile option to choose. They mainly feature success love stories where the female is a size 1 blonde. They do not make it clear not all internet browsers work well with their site.
No complete free trial to decide if this site is to your liking, you find out after you pay.
Lots of NON Christians and technical problems.

They have an attachment of another site called: Believe.com which offers bible study and Christian articles.
Non Christian and tricky.
