MeliaeSVG Icon Theme is an icon set created by sora-meliae. It is quite clean and very refreshing icon theme. Love the simple and cleanse look of the icons.
It is for Gnome, and i am using KDE so how can we install it inside KDE desktop. That is quite easy. 1st download the zip file from deviantart. Extract the zip archive, a new file with .tar.gz will be extracted.
Now open ‘Configure Desktop’ in KDE from kickoff menu. Click on ‘Application Appearance’ and choose ‘Icons’ and click on ‘Install new theme’, browse for the theme which you just extracted(.tar.gz one). And bingo, there you go.. apply it and you will see the changes immediately.
