High-Contrast-Inverse-Spectrum

INSTALL

To install, place each theme folder in the (.themes) folder in your home folder. If that folder doesn't exist, create it. It will be a, "hidden," folder, so you may have to enable the showing of hidden files and folders in your file browsing program. For Caja this setting can be found under (edit>preferences).

Also, perform the following, in a terminal, as root or with sudo:

apt install qt5ct qt5-style-plugins

After that, you can run the following, in a terminal, as your normal user:

qt5ct

From this program you can select gtk2 under the (style) selection. Qt5 applications will subsequently render the gtk2 portion of the themes as well.

That should be it. Modify these instructions as needed for non-debian-based distributions. If qt5ct gives you an error/warning that prevents it from functioning, as it might, just search the Internet for the particular error; there should be a solution.

ABOUT

These themes are a modification of the default theme, "High Contrast Inverse." Essentially it came down to using the Pluma text-editor and a lot of the, "find and replace," function.
It's all based off a now dated version of that theme, which came with a particular version of the Mate Desktop Environment, of which I can't recall.

There may be bugs and the themes are far from organized and perfect; but, after hacking away for some time, things look nice enough that they have been usable for me, for some time now. I've been meaning to upload and share my work for some years now; but, things were never polished enough for me to feel it was worth doing so. Anyway, I finally expanded the intial red theme to an entire color set, cleaned things up a bit, and here we are. As of Mate version 1.20.4, these themes still seem to work. Hopefully they will continue to function nicely for some time...

This theme seems to be covered under the GNU Lesser General Public License in the official Mate git repos (I think?); so I've included it here.
So, should you, for some ungodly reason, decide to modify this mess; make sure you follow the terms of the GPL.
