Could not find a navbar background that fits with my logo [migrated]

I recently changed the logo for my company but now it does not fit anymore on the navbar. The color of the logo are #3331a1 and #a8b0c6. I don't really want to have a white navbar but seems to be the only option. I am also willing to modify a bit the color of the "HR". Do you have any suggestions for the navbar color?
