Problem
Glow effects around text merge with bright backgrounds and reduce letter separation.
Solution
Root Cause / Diagnostic:
Using additive "Screen" or "Linear Dodge" outer glow blending modes behind text layers fails when placed over high-luminance background elements (e.g., bright skies, white walls, studio softboxes). The glow elevates local background exposure to pure white, washing out letter silhouettes.
Actionable Fix:
1. Replace light-colored outer glows with dark drop shadows, dark outer strokes, or solid high-contrast backing banners when overlaying light backgrounds.
2. If an aesthetic neon glow is required, place a dark under-shadow layer (Multiply mode, 60% opacity) beneath the neon glow to preserve edge contrast.
3. Desaturate and inspect the thumbnail in grayscale to ensure minimum 4.5:1 luminance contrast ratio between letterforms and background assets.
Pro Tip:
Never rely on bright outer glows for text legibility; outer glows are decorative flourishes, whereas hard dark strokes and drop shadows provide the structural contrast needed for instant mobile scanning.
