White text contains colored fringe pixels after anti-aliasing against a removed background.

Problem

White text contains colored fringe pixels after anti-aliasing against a removed background.

Solution

Root Cause / Diagnostic:
Extracting or cutting out white text from a previously colored background leaves colored anti-aliasing transition pixels along letter contours. When placed onto a new background, these leftover fringe pixels make typography look blurry and discolored.

Actionable Fix:
1. Never cut out rasterized text from old images; recreate all typography from scratch using native vector type layers with crisp anti-aliasing.
2. If working with legacy raster assets, clip a pure white Color Overlay layer style onto the text layer or apply a 1 px minimum contract filter to the selection mask.
3. Zoom to 400% on letter edges to confirm edge pixels transition cleanly from pure white to background without chromatic fringing.

Pro Tip:
Always type headline text fresh using native vector text layers; cutting out pre-rendered raster text carries over ugly fringe pixels that make text look blurry.
