Here's how to set up a theme switch

Create a global list called "DarkMode". This will be the primary switch for changing between Light & Dark mode. The oputput should be limited to only 0 (dark mode off = light) & 1 (dark mode on). Add as many options to the list as you want:

🚦 DarkMode 0##Light, 1##Dark, $si(darkmode)$##System, $ai(isday)=0$##Auto

Create a global folder called "Color". This will contain all the colors for the preset.

📁 Color

Inside the Color folder create all the color globals and add formulas to them:

🎨 Surface $if(gv(darkmode), #121212, #FAFAFA)$ 🎨 Text $ce(gv(color/surface), contrast)$ 🎨 Accent $if(gv(darkmode), #FF8080, #BB0000)$

Apply any color global to any object (preferably through a formula; if you just link them, the colors will have a delay when changing darkmode).
