EDIT – Aug 8th, 2016: studiostyles now supports Visual Studio 2015. I recommend getting WekeRoad Ink from there, as it may include other options my version doesn’t have.
For some time now I’ve been a fan of the WekeRoad Ink editor theme for Visual Studio. I used to prefer Son of Obsidian, but I’ve come to feel that WekeRoad’s muted colour palette actually helps draw the eye more readily to different parts of the syntax. So of course the first thing I would do, upon installing Visual Studio 2015 for the first time some months ago, would be to get my fonts and coluors back to preference.
Unfortunately studiostyl.es only offers 2010 and 2013 versions of Visual Studio settings files. I decided to give it a try anyway, hoping that enough would translate from 2013 to 2015 that I could at least get the syntax colouring back… But, no dice.
So recently I spent a little lazy time mapping the colour settings for WekeRoad Ink to Visual Studio 2015. A few things have changed in the colour and syntax highlight settings, enough at least to mean the settings are no longer backwards compatible, but I was able to translate pretty much everything. I’m not sure when (or if) studiostyl.es will add support for 2015 themes, but for now you can download my version and import it into VS.
Note, this is only syntactic colouring, anything else that studiostyl.es might provide probably isn’t preserved.
While I’m talking about customizing the editor in Visual Studio, my current favorite font, Hack, is a nice option if you’re looking for a change of style there as well.
