You can find a step by step explanation on how to set a dark theme for Texstudio
http://www.pauljhurtado.com/latex/texstudio.html
scroll down to section Dark Color Theme for TeXstudio Editor
Here is a copy/past of the instructions:
Dark Color Theme for TeXstudio Editor
Instructions for installing a pre-configured dark theme for the TeXstudio editor:
- Download a dark color theme:
- My dark theme:
Texstudio-dark-Hurtado.txsprofile
- Various examples at http://tex.stackexchange.com/questions/108315/how-can-i-set-a-dark-theme-in-texstudio.
- My dark theme plus some editor modifications (e.g. supressed underline of grammar mistakes, etc.):
Texstudio-darkplus-Hurtado.txsprofile
- Open up the color theme in a text editor (I prefer notepad++).
- Next come the "not-so-user-friendly" steps, so let me walk you through them!
- Go to Options > Save profile... and save a backup of the current profile to something like
user-default.txsprofile
.
- Do this again, but instead save to a file named something like
custom-dark1.txsprofile
. Note the directory this file is saved it!
- Open
custom-dark1.txsprofile
(or whatever you named it) with a text editor (again, I like notepad++) and scroll to the very bottom which should look like
...
[formats]
version=1.0
Note these are the first two lines of the dark theme file you downloaded!
Copy and paste the contents of the dark them to this section of custom-dark1.txsprofile
file and save. The [formats] section of custom-dark1.txsprofile
should now read
...
[formats]
version=1.0
data\normal\priority=-1
data\normal\bold=false
...
- Go to Options > Load profile... and load the newly edited
custom-dark1.txsprofile
.
- Restart TexStudio and open a file, and you should see the dark themed editor!
- Finally, you can further modify your color scheme by going to Options > Configure TeXstudio > Syntax Highlighting
