If You klick in Firefox with the right mousekey at the logo and then at 'Inspect element'(Q) in the opening menu - then you can see the code which generates the logo -.the eqivalent code in the bootm-menu makes the logo blue.
You can You give me an example site - which version of gpeasy do You use ?
It may come with the <?php gpOutput::GetHead(); ?> in the template - which You can disable for test. (https://www.typesettercms.com/Docs/Output_Functions)gpOutput :: GetHead (); loads all components of the header that are controlled by gpEasy. These are, for example, the page title <title>, meta keyword, the meta description, the layout style sheet used and some other css and scripts.
gpOutput :: Get ("Extra", "header"); loads the logo block, which is editable for the admin.
Another 'bad' solution is to create a white 3px-picture in irfanview (or other) and then save it as mini-logo.png (rename the other before) and set the transparent color to white. This leaves the image which is invisible.
