Sometimes a change of colour can create a change of mindset. This is one of the reasons I started creating my own Ableton Live skins, now themes. I'm back with five fresh themes for Ableton Live 10 for you. They're a mix of light, medium and dark ones, making them useful for different situations (I prefer lighter themes during the day, darker ones when I'm producing into the wee hours).
Get more free themes. You can still download the Live 9 skins. If you don't know how to install them, have a look at this tutorial, and if you'd like to create your own themes, I've got a tutorial for that as well.
