Within the Enterprise version of Natural HR you can change the colours of the menu bars and main buttons to be more in line with your company brand. You can do this under:
Administration > Company > settings > Display settings - scroll down to the Branding section
Menu colour - the colour across the top and left menu bar
Primary button colour - used as the "highlight" colour in the menu and main buttons throughout the system such as the "Submit" button
Secondary button colour - used for additional buttons where there's a few to choose from and these are typically the less well-used buttons
If your corporate colours are especially bright, it would be worth asking your marketing team for some options as they'll usually have a secondary colour pallet to choose from.
Darker colours work better than greys on the menu as the menu items are off-white.
Depending on your colour scheme, an all-white logo may look better in the top menu bar - here's how to change your company logo: https://support.naturalhr.com/article/565-uploading-your-company-logo
