Great car mats
Response from exactmats.com
We've had a few inquiries for colored mats, but not usually for this particular reason. Of course, we're always looking to add new products to our website, so we've gone ahead and forwarded your product idea to our team, but we also want to see if we can help troubleshoot the issue you are experiencing.
We've found that there really should not really be too much dirt (if any) under the mat at all. After all, the goal is to keep the carpeted mat clean. Ideally, you'd clean the floor mat under the ExactMat before installation, and then place the ExactMat on top to keep the dirt from getting underneath.
If you have time, feel free to reach out to us. We'd be happy to provide you some tips!
