I already have my blog title in my custom header image so want to remove the blog title that automatically appears above the header image. I'm sure I should be able to achieve this by making the title the same colour as the background rendering it invisible since in the Mistylook theme under Presentation > Custom Image Header it states...
"This is your header image. You can change the text color or upload and crop a new image."
However, there appears to be only the facility to upload a new header image and none to change the text color. My blog is at http://guerrillascience.wordpress.com. Any ideas how I can make the blog title invisible?
