The three colors on the graph are yellow, orange, and pink. What does the orange represent?
It’s where the two colors mix. If you look at the GlassWire UI the bottom left shows the up/download colors with small arrows.
If you have trouble seeing the default colors I recommend using “Blue & Peach” or “Aqua & Pink” under the “Skins” at the top left “GlassWire” menu.
