What Is Delta E?

Delta E (ΔE) is a metric for quantifying the difference between two colors. It represents the "distance" between colors in a color space, often used to measure color accuracy in various industries.

Key points about Delta E:

• Scale: Lower values indicate smaller differences. A ΔE of 1 is typically considered the smallest difference visible to the human eye.
• Use: Commonly used in printing, photography, and display calibration to ensure color consistency.
• Interpretation:

Different formulas exist, such as ΔEab and ΔE00, which account for perceptual differences more accurately.
