In macOS, transparency – or more properly, translucency – is a visual effect many apps use to create a sense of depth by hinting at content residing in the background.

An example of transparency is when content behind a window shows through in interface elements like menus and sidebars. It's evident in the screenshot above, for example, in which the colors of the desktop wallpaper bleed through the sidebar in the Photos app.

A similar effect is sometimes used within app interface elements that are windowed, allowing window content to show through other elements like toolbars. An instance of this can be seen below, where the folders are visible through Finder's toolbar as if through frosted glass.

The effect can look cool, but it can also be distracting if you're trying to focus on content, especially if you're editing photos. Fortunately, macOS lets you turn off transparency, but the way to do it isn't immediately obvious. The following steps show you how.

Setting your Accent Colour to Greyscale also turns off wallpaper window tinting. Another tip to increase legibility.

Does this save resources at all? I used to do this on my iphones back in the day thinking I saved CPU cycles and ram.
None of this makes any difference on modern computers.

There's no accent color called "Greyscale". It's called "Graphite".
You still knew which colour I was talking about.
I hope you realize that's an issue with whatever third-party browser and/or theme you're using.
I hope you realise they were being sarcastic.

Stop being obtusely fastidious.

I still do this on my iPhone XR (started with the iPhone 5 and iOS 7). It’s less about resources at this stage, and more that I’ve come to prefer low transparency and reduced motion.
Same here! I thought I was the only one that did this. I am so happy to have found Reduced Motion for my MacBook thanks to this article, all these years I had no clue it existed (same for transparency for Mac OS). I've used both since my 6+ iPhone and prefer it.

Recent betas remove the window tinting when using any accent color with reduce transparency enabled (I'm on 10.14.3 Beta (18D21c)). This is great. Tinting still remains in the dock, notification center, and alerts - no big deal, window tinting was the one that was really annoying.

Really wish I could get rid of this dropdown menu transparency, it's almost a deal breaker for me.
