How to change base color of Prism Theme

How do I change the area that is purple in this screenshot? I’ve been through all the color customization options and I don’t see one. If it’s custom CSS that’s fine, I don’t want to change everything, literally just that one area. It seems like it should be really simple but somehow I’m missing it.

Thanks

You linked to a fairly old screenshot.

The above is what the top of Prism looks like with a few tabs open, all default settings, in my vault.

Are you looking to change the tab and accent color used in a few different places? That appears to be controlled from here, the Accent Color Preset.

Ah, okay, I didn’t realize how old the screenshot was. The color I’m trying to change is the gray in your second screenshot. I think Prism just no longer has the ability to customize the part I want to customize without learning more coding that I’m not willing to look into right now lol

Thank you!

Got it.

That area looks to be set by --background-secondary, so you could change it with this, for example:

body.theme-light {
    --background-secondary: hsl(0, 0%, 80%);  /* hsl(0, 0%, 93%) */
}
