blend mode for title and menu

[pk]

Hello out there
can somebody tell me how I change the blend mode for the title and menu? Currently I have the problem that the title is not displayed on the black sites. I would like to use the exclusion mode.

I will be thankful for help
regards David

Dear David @pk

Could you post a link to your website for a better look :)

If not i assume you are looking for this? :

.sitetitle {
    mix-blend-mode: exclusion;
}

Let me know :)

Best
Richard
