Foreglow Theme

Foreglow is a twilight-inspired theme for 400+ applications, based on real twilight sky color theory. A narrow band of cool hues (blue → violet → magenta) dominates the palette, while a small complementary wedge of warm hues (orange → gold) breaks through at the horizon — exactly what makes a sunset read as glowing rather than muddy.

Variants

• Foreglow — Dark theme (twilight night sky)
• Afterglow — Light theme (twilight dawn sky)
