Gimp 3.0 is still in active development, with new features being added on a daily basis, but a dev version is currently available.
The most current Gimp development version is 2.99.12, which offers plenty of new features and UI tweaks. Gimp 3 lacks themes and plugins because it is still under development. This is why I wanted to make some themes for Gimp 3.0, however you can still use them in the development version.
Before I show you any of my themes, I want you to know that I am still very new at GTK theming and that I take inspiration from other applications as well as create my own custom themes, so there may be some inconsistencies, but I will fix them in the future, or you may change them if you know how.
How to download and apply these themes
First, download the GIMP 3 theme file.
Then Extract The file.
Then Find the GIMP Theme folder
Then Paste the extracted gimp theme file to the gimp theme folder
Photoshop Black v2
This is the second version of the Photoshop theme that I have created; I will continue to improve it, and if you have any ideas for it, feel free to tell me or create an issue on the GitHub page.
Affinity Photo Black
Another theme inspired by another commercial image editor, so if you like affinity Photo’s design, then this is for you. I thought about adding gradients to the sliders.
Photoshop Black
Another Photoshop-inspired theme, this is a Photoshop theme with more dark blacks, so feel free to use if you like darker themes.
DaVinci Resolve Black
Resolve is not a photo editor tool, but it is a very famous piece of software, so also tell me what you like about it. The theme color is a little tinted, so it is not fully neutral.
Deep Blue
Another heavily tainted theme; many people might not like it now, but I hope it’s for someone.
