Moderncv with XeLaTeX unintentionally in different colour for first and last name

I am using moderncv for my CV with XeLaTeX. When I compile the document below, the first and last name appear in different shades of grey. I would prefer for both to be the same colour. If I leave the first name blanc and post first and last name in the second bracket, I receive the desired result but this results in misalignment because there is still a white space for the first name. Any idea how to solve this problem?

If you look in the Customization section of the documentation it explains how the various colours are set. So you can use:

To change the colour of the first name to be the same as the last.

You can change the lastnamecolor and firstnamecolor to whatever colour you like:
