How to Read Delta-E Scores
Color Science, Not Guesswork
ShadeVault uses the CIEDE2000 Delta-E algorithm — the industry standard for perceptual color difference. We convert swatch colors to CIE L*a*b* color space and compute the distance between them, accounting for how the human eye actually perceives color differences.
Frequently Asked Questions
How does ShadeVault match foundation shades?
ShadeVault uses the CIEDE2000 Delta-E algorithm to compare swatch colors in CIE L*a*b* color space. This is the industry standard for measuring perceptual color difference, accounting for how the human eye perceives color variations.
What does the Delta-E score mean?
A Delta-E score of 0-2 means the colors are nearly identical (imperceptible difference). Scores of 2-5 indicate a great match visible only on close inspection. Scores of 5-10 show similar colors with noticeable differences. Above 10, the colors are clearly different.
Can I find a drugstore dupe for my high-end foundation?
Yes! Use the Foundation Shade Matcher to search for your current shade, then filter results by price range to find affordable alternatives with similar color matches across brands.
