JetBrains IDE dark theme based on `Darcula Solid` with extra darkness and a little bit of red. Inspired by `Material Black Cherry` theme for GNOME (and made to match it in the first place).

• Go to Settings (Preferences) → Plugins, find the theme plugin and install it
• Restart the IDE
• Go to Settings → Appearance & Behavior → Appearance and select Solid Cherry in the Theme dropdown
• (optional) Go to Settings → Editor → Color Scheme and select Solid Cherry in Scheme dropdown, which will correct several editor colors (e.g., git diff backgrounds) to the ones better matching the theme (should be done automatically, but just in case)
