Here’s a very red room at The Madonna Inn in San Luis Obispo, California. They named it the Tack Room. It has red leather wall covering, red leather bedspreads, red stained wood walls, pink marble pedestal sinks, and lots more red stuff.
The Madonna Inn has 109 unique theme rooms where you can stay, as well as multiple odd over-the-top dining environments. You can/should see photos of all 109 rooms here.
