Color Distance Calculator
Measure the perceptual difference between any two colors using delta E and standard math formulas
Advanced Distance Metrics
Euclidean Distance
Standard geometric distance in RGB space
√((r₁-r₂)² + (g₁-g₂)² + (b₁-b₂)²)Manhattan Distance
Sum of absolute differences in RGB values
|r₁-r₂| + |g₁-g₂| + |b₁-b₂|Chebyshev Distance
Maximum difference in any RGB channel
max(|r₁-r₂|, |g₁-g₂|, |b₁-b₂|)Delta E (CIE76)
Perceptual difference in LAB color space
√((L₁-L₂)² + (a₁-a₂)² + (b₁-b₂)²)Perceptual Distance
Weighted RGB distance based on human perception
√(2(r₁-r₂)² + 4(g₁-g₂)² + 3(b₁-b₂)²)Interpretation Guide
Euclidean & Manhattan algorithms calculate raw distance in the RGB cube. While computationally efficient, they don't always mirror the nuances of the human eye.
For commercial branding and professional print work, always prioritize Delta E (CIE76). It is the gold standard for verifying color accuracy in design systems.

FAQs
What is color distance and why is it important?
Color distance measures how different two colors appear, either mathematically or perceptually. It's crucial for design consistency, accessibility testing, color matching, and more.
What is Delta E?
Delta E (CIE76) is a color difference metric that measures perceptual distance in LAB color space, which better represents how humans see color.
