[Solved] Change User Dashboard Left Sidebar Color?

Is there a way to change the color of the user dashboard > left sidebar? The journal logo has a transparent background and the text in it is black. Therefore, the dark blue (#002c40) sidebar color is not showing the text in the logo image. I don’t want to change anything in the backend that would cause it to break, just the sidebar. Really appreciate any help I can get. Thanks!

I was able to resolve this issue by modifying the lib/pkp/templates/common/header.tpl code, where it has the IF header_logo exists for the frontend, it sticks the same logo to backend. I just copy pasted ELSE into IF, so no matter it will only show the logo I need to show in the backend. Not sure if there was any other easier way. Do share if you know!
