Need Blue / Black theme Similar to a particular site

Hi there

I’ve developed a few sites in WP for friends etc, and I need a theme to replicate the features and “look” of the following site as much as possible:

https://www.workplatformltd.co.uk/

(certainly, the colours and style…not 100% the same maybe, but as close as)

Any suggestions?

I quite like the look of: https://siteeditor.net/free-themes-wordpress/photabulous-dark-blue-photoblog-free-wordpress-theme/

…but I’m not sure.

Cheers! Any suggestions welcome!
