Color accent under "Video Tools" and "Application Tools"

Hi, I'm new to this forum.

I have set a dark theme with dark red accents for the Windows explorer. However, when I select an application or video, these options appear above the ribbon and for some reason they are highlighted pink and lilac respectively, as shown in the screenshot. Is there any way to change this so it's the same dark red I've chosen for my accent color?

Thanks for your help.
