Used icons are from the Numix only for applications other icons in the navigation and so on, all unique from the author developer Roman Nguyen.
Additionally I might add, this theme is created specially for Ubuntu. And if you use the installation script that is in the archive, we install many unnecessary packages and files that are not suitable for my favorite Linux Mint. So we take only what we need.
After you install the theme you will have 3 sub-themes:
On screenshot you see is a combination of two themes.
Installation latest version into Linux Mint:
Follow these five commands
cd /tmp; wget https://github.com/btd1337/Stupendously-Hot-Charmander/archive/master.zip -O Charmander.zip unzip Charmander.zip && cd Stupendously-Hot-Charmander-master mkdir ~/.themes; mv theme/SH-Charmander* ~/.themes/ mkdir ~/.icons; mv icon-pack/Charmander-Circle/ ~/.icons/ mv icons/* ~/.icons/Charmander-Circle/48x48/apps/
That's it, now you can go to System Settings and select one of the installed themes and icons.
