How do I change the background color for SnapGene windows?
Users of SnapGene 6.1 or later, see Configure Dark Mode and Background Color
For SnapGene 6.0 and earlier, the default background color is "Off-White".
Open Preferences
Click SnapGene → Preferences (macOS) or Edit → Preferences (Windows or Linux). If necessary, select "General" in the sidebar.
Click the "Background Color" drop-down menu to choose from a list of predefined colors, or choose "More Colors..." to define a custom background color.
