Download and extract the folder to you "themes" folder in LMMS. (You might have to extract twice to actually get the folder) It can be found where you installed lmms. Then go to settings in LMMS and change the theme sourcefolder to the "All Dark Blue" folder. Restart of lmms is needed.
If you think some of the icons or the splash screen aren´t your style, you can copy and replace those files with the ones from the default folder/ the default theme. I have made blue, nearly everything I could have made blue, so that you can modify for yourself the blueness.
(Even if I have chosen the wrong license above) You are free to copy and modify this theme. You are not allowed to sell it as it is though.
