Changing Header scrolled logo

Hello,

thank you for the theme you created, I only have one question for now.

When the website is scrolled down, the header color changes to white, and as our teams logo is white/green and black/green, and the normal header color is black, we can’t use the same logo.

So, the question is, is it possible to change the logo for scrolled header, and if it is, how can it be done? Here is the website: http://ritehracingteam.uniri.hr/

Thank you in advance
