What Is Image Color Replace?

Swaps a specific color with a replacement color using Euclidean RGB distance matching. Tolerance controls how similar pixels must be to match. Preserves luminance variations for natural results.

Why Use Our Image Color Replace?

  • Color pickers for precision
  • Adjustable tolerance
  • Preserves luminance variations
  • Per-pixel color distance matching

Technical Guide

Distance = sqrt((r1-r2)²+(g1-g2)²+(b1-b2)²). Tolerance maps 0-100 to distance 0-441. Replacement preserves luminance offset for natural shading.

Tips & Best Practices

  • 1
    Start low tolerance (10-20)
  • 2
    Higher tolerance may affect unintended colors
  • 3
    Solid colors are easiest
  • 4
    Check preview carefully
