Added RGB color test sequence commented out in the display initialization code:
- Red screen fill (0xF800)
- Green screen fill (0x07E0)
- Blue screen fill (0x001F)
- 2-second delays between each color

**Currently:** No functional impact - the test code is commented out, so it doesn't execute.

**If uncommented:** Would add a 6-second RGB test pattern on display startup, useful for verifying:
- Display color channel functionality
- Proper RGB565 color format support
- Screen initialization success

This appears to be debug/diagnostic code left in for future troubleshooting.
