This is a modified version of Breeze Dark with the colors all unsaturated and darkened.
I put this together because I work with graphic design and video in KDE and sometimes you need neutral colors in your UI so as not to throw out your perception of colors in your work.
Goes well with the Breeze desktop theme (regular, not light or dark version), Breeze Snow cursor and Breeze Dark icon set. Recommend using regular Breeze as your GTK theme also.
Kdenlive should pick up this theme automatically, but to use it with Krita go to your resources folder, create a subfolder in there named "color-schemes" and drop the Unsaturated.colors file in there. To find your Krita resources folder run Krita and go to Settings > Manage Resources then click the "Open Resource Folder" button on the window that pops up.
I'll probably put out a set of Konsole colors and a Look & Feel package to go along with this at some point too.
