HardHacker Theme for many Apps

This is a comfortable dark theme that's visually pleasing and compatible with multiple apps, with more support to come. The theme's color palette was inspired by some cyberpunk-style artworks. Initially, we wanted to create a cyberpunk-style theme, but found that the neon lights and brightness commonly found in cyberpunk-styles were not suitable for long-term reading. So we lowered the saturation and brightness while keeping the cyberpunk-style colors to make the theme more comfortable. At the same time, we ensured that the color scheme is colorblind-friendly. Enjoy it! 🎉❤️
