remove global inline styles breaks some colors

Hi,
Perfmatters' last version bring a feature called "Remove global Styles". https://perfmatters.io/docs/remove-global-inline-styles-wordpress/
"Most users probably won’t be using this feature, and the problem is that this adds 311 lines (unminified) of code to every page of your WordPress site."
It seems it is good feature to make my website faster.

I have used it but my font colors broken in the footer, which created with GenerateBlocks free.
I have asked about this to developer and get this reply. https://prnt.sc/26v646e

Is there any way to get rid of duetone styles and make this feature work?

thanks
