Increasing text contrast in Via browser

I'm using the Via browser on my Pixel 6. Really like it except for one problem. The white text on black background doesn't have enough contrast to be easily readable. It's really more like gray on black. I could go to white background, but I like the black background, just want it to be easier to read the text on web sites.

My question is whether there's a way to do this in the browser, or if I need to go into the phone's accessibility menus and increase the contrast there. The Via browser is the only place where I need to increase contrast, so I'd naturally like to do it there.

Thanks.

 

Yes, there is a dark mode...that's the mode where the text contrast needs boosting. I've switched off "night mode" for the moment, but don't like the white background. So I'd like to be able to go back to night mode with brighter web site text.

 

Just switched to duckduckgo browser on my phone, so no longer need this question answered.
