You can customize *all* PixInsight colors and fonts by editing the core CSS file. These are the steps:
1. Locate the .qss file for your platform:
x11.qss for Linux and FreeBSD
osx.qss for Mac OS X
win.qss for Windows
This file is on the bin installation folder. On Windows, this folder is by default:
C:\Program Files\PixInsight\bin
and on Mac OS X:
/Applications/PixInsight.app/Contents/MacOS
2. Open this file with a good code editor. For example, you can use PixInsight's Script Editor.
3. Go to line # 1358 of the qss file. Here you'll find the relevant items to customize the Process Console and command line windows:
QWidget#CWConsole, QWidget#CWCommandLine {
background: #202020;
color: white;
}
4. Change the background and color properties as desired. For example, a classical freak combination is:
QWidget#CWConsole, QWidget#CWCommandLine {
background: black;
color: green;
}
If you want different colors for the console and command line windows, you can split the above declaration into two separate classes. For example:
QWidget#CWConsole {
background: black;
color: green;
}
QWidget#CWCommandLine {
background: black;
color: yellow;
}
Let me know if you need more information. I plan on releasing a complete "Guide for PixInsight skinners", time permitting, but we have other priorities right now.
