Problem
Background texture competes with headline typography because both have similar spatial frequency.
Solution
Root Cause / Diagnostic:
High-frequency visual textures such as brick walls, foliage, or noise patterns contain sharp luminance variations that mirror the stroke frequency of text. When text is placed directly over these busy textures without depth separation, the letter edges blend into background contours. This creates severe optical camouflage that destroys headline readability.
Actionable Fix:
1. Apply a 15px to 25px Gaussian blur to background texture layers specifically beneath typography to suppress high-frequency noise.
2. Insert a solid or gradient backing card with a minimum contrast ratio of 4.5:1 against the headline letterforms.
3. Verify legibility by converting the composite image to grayscale; text must remain instantly readable without color assistance.
Pro Tip:
Contrast in luminance and texture frequency is far more critical for instant mobile readability than chromatic saturation.
