Discourse Vincent theme

This post is a WIP

Beta testers needed for a new theme.

Theme repo:

GitHub - discourse/discourse-vincent-theme: v0.77

Compressed Screenshots:

will look much better on your screen, image compression cases artifacts / blur. Also, I will update the screenshots as the theme takes shape

Color schemes

Vincent Dark Blue

Vincent Dark Red

Vincent Dark Green

Vincent Dark Magenta

Vincent Dark Orange

Vincent Dark Teal

custom backgrounds

(these are samples only, you need to provide your own background images)


Don’t forget to set the color scheme to one of the color schemes that come with the theme

The thin header is optional. If you want the thin header you need to add a theme component which you can find here:

This is a beta theme. Kindly report any issues in this post.

Feedback / suggestions welcome


Anyone having issues with creating Categories? Everytime I click the hamburger menu it just adds a “+” under neath and does not take me anywhere.


Same behavior here :frowning:

I’d not noticed, as I haven’t created a new category for a while.


I just tested this and am running into the same issue. It seems that the code that’s used to create the category admin dropdown has changed on Discourse. Updating the theme to use the following code to create the dropdown seems to fix the issue:

{{#if showCategoryAdmin}}
    onChange=(action "selectCategoryAdminDropdownAction")

We will get this fixed very soon.


Newbie question but where would I apply this?

I applied it by editing the theme’s /head section. I replaced this block of code:

  {{#if showCategoryAdmin}}


  {{#if showCategoryAdmin}}
      {{categories-admin-dropdown onChange=(action "selectCategoryAdminDropdownAction") }}

Having to manually edit the theme isn’t ideal though. We will get this fixed so that the change can be made by clicking the theme’s “Update to Latest” button.


How can I change the main text color of this theme?

Also this issue still continues:

Those ‘‘new’’ and ‘‘unread’’ menus should be invisible unless there’s a new topic as it is on original Discourse theme.

Is it still on progress?

Yes, same thing for me. I fixed it by switching to a different them, creating the category, then switching back to the Vincent theme.

How do I get access to the extra color schemes shown in the original thread? I want to switch to the Dark Green one but I only see Vincent Dark available in my settings.

Since this topic has been moved to #theme:broken-theme, it seems likely that this theme is no longer being maintained. I have a set of tweaks I use on our forum with a chrome extension since vincent worked well enough on its own, but we didn’t have the resources to maintain our own fork. They’re a little bit opiniony, make some tweaks for personal taste, don’t cover everything, and may be a little outdated or intended to fix bugs that were fixed officially by now, but maybe they’re useful to someone.

One of the most beautiful themes. :heart_eyes:

Why did you stop developing the theme @Johani? I can help with a sum of money if you or someone else can continue the work for all of us.
