Looking for a dark theme? Here's how you can get one working using a browser extension (unofficial!)

My friend pointed out a dark theme extension for Chrome, Firefox, and Safari (webpage: https://darkreader.org/). It's good at converting light theme websites to dark theme ones. Surprisingly, it even works with Onshape! I added this to the config (under Dark Reader extension button > Dev tools) to make the icons more readable and dark theme-y:



.os-svg-icon {
    filter: brightness(0.6) contrast(5) saturate(2) grayscale(.2) !important;

It works very well with the documents page, part studios, feature studios, assemblies, etc. The only place where it really fails is in drawings (the drawing stays light and the icons are hard to see), but you can quickly toggle it on and off with Alt + Shift + D.

Here are some screenshots with it active:

Of course, I'm not a developer or in any way affiliated with Onshape or Dark Reader, so use at your own risk!

    Do you have the issue with dark reader turning the background white when editing certain features?

    Thanks for showing how to fix the icons too 👍

    I just noticed the background turning white. I somehow had managed to not test editing anything other than a sketch before posting :s. Hopefully I'll figure out a workaround. In the mean time, I will unfortunately probably have to stick with the filter and filter+ options which cause the model's shading to be inverted (however, it does preserve the correct hues then). At least the dynamic dark theme option is good for viewing and presenting.
