For instance, GitHub<\/a> pages may be in dark mode<\/a> when logged out and not when logged in.<\/p>\n

Sample GitHub page<\/a><\/p>\n

Change to dark mode<\/h2>\n

When logged in<\/em><\/strong>, click on the profile picture in the upper right → Settings<\/a> → Appearance<\/a> (in the left panel). Set Theme mode<\/em> to “Single theme”<\/em>. Select “Dark high contrast”<\/em>.<\/p>\n

When logged out<\/em><\/strong>, click on the “Appearance settings”<\/em> icon in the upper right. Enable “Dark mode” (the last item).<\/p>\n

Though it may not actually change to dark mode… It may also be “Open application menu” (in the upper right) → Settings…<\/a> (about 70% down) → “Language and Appearance” (about 25% down (scrolling may be required)) → “Dark” (the last of the three options)).<\/p>\n

In fact, that is Firefox’ setting, not GitHub’s. Enabling JavaScript is not even required.<\/p>\n

Bonus: Change to dark mode in LibreOffice<\/h2>\n

Menu Tools<\/em> → Options<\/em> (shortcut Alt<\/em><\/strong> + F12<\/em><\/strong>) → Application Colors<\/em> (left panel, in “LibreOffice”<\/em>) → Document background<\/em>. Also change “Font color”, for example, to orange.<\/p>\n

Note: This location may depend on the version. For example, in the Danish version 25.2 (February 2025), it is in menu Funktioner<\/em> → Indstillinger<\/em> (shortcut Alt<\/em><\/strong> + F12<\/em><\/strong>) → Udseennde<\/em> (left panel, 8th item in “LibreOffice”<\/em>) → Tilpasninger<\/em> (in the right panel) → Elementer<\/em> → Dokumentbaggrund<\/em>. Also change “Skiftfarve”, for example, to orange.<\/p>\n

Though it will only change the spreadsheet itself, not the menus, toolbars, status area at the bottom, etc.<\/p>\n

To refine it, use the colours from well-known colour schemes, e.g., Solarized<\/a>. For Solarized, the default is base0, base03 (foreground colour, background colour), where base0 is RGB 0x839496 (HSV 0x842096, 132 (angle 186°), 32, 150) and base03 is RGB 0x002B36 (HSV 0x88FF36, 136 (angle 192°), 255, 54).<\/p>\n

These can be entered in “Custom Color”, under “RGB”, in the “Hex #” field:<\/p>\n
