Dark-mode UI screenshots become too black after contrast enhancement and lose internal hierarchy.

Problem

Dark-mode UI screenshots become too black after contrast enhancement and lose internal hierarchy.

Solution

Root Cause / Diagnostic:
Applying aggressive global curves or high-contrast filters to dark-mode software interfaces crushes dark-gray background tones into pure #000000 black. This causes subtle UI borders, container boxes, and secondary buttons to vanish into an undifferentiated void. The software interface loses its structural context and looks broken.

Actionable Fix:
1. Apply targeted Curves adjustments specifically lifting shadows (RGB levels 10–30) to preserve distinct container boundary lines.
2. Add subtle 1px inner borders (#2A2A2A) or faint backlights behind dark UI windows to preserve window separation.
3. Verify tonal separation between deep black backdrops and dark charcoal software containers on standard IPS and OLED displays.

Pro Tip:
Never crush dark-mode UI blacks; lifting dark grays slightly keeps software interfaces dimensional, clean, and immediately recognizable.
