Post title not changing color

I am changing the hex value of the post title like I always do and for some reason it is not changing.
I have tried deleting the post title and placing it inside the post but it stays there. I have emptied the cache and restarted my machine. Not sure what else to try. Any advice?

I am using version 3.53 and here is the url: http://www.drphyllisritchie.com

Thanks for any help or advice!
