gloomy fireplace

[lcc]

Hi, my fireplace was originally built of some yellowish-brown brick. The color is very gloomy, especially the mirror next to it is the darker color mirror. So, I painted it with a light beige (or light yellow)color. Now, I think it looks kind of childish. I heard that there are some fake stone or fake brick which I can glue (?) on to it. Can someone give me advice. I will love to see genuine brick/stone appearance.

Thanks,
