**Issue**: Color theme button colors were too similar to other buttons
- Light mode (sun): Orange #f39c12 - same as keyboard button
- Dark mode (moon): Blue #3498db - same as zoom button
**Fix**: Updated to more distinctive colors
Light mode (sun):
- Was: Orange #f39c12 (same as keyboard)
- Now: Gold/Bright Yellow #ffd700 (distinct sun color)
Dark mode (moon):
- Was: Bright Blue #3498db (same as zoom)
- Now: Dark Slate Blue #2c3e50 (darker "nighty" blue)
Auto mode:
- Kept: Purple #9b59b6 (already distinctive)
**Result**: Color theme button now has unique, semantic colors that
clearly represent sun (bright yellow) and moon (dark night blue) without
conflicting with other buttons.
Updated both hover and at-bottom states for consistency.
