Table 1 Suggested interpretation of ΔE values
From: Study on the color levelness of silk fabric dyed with vegetable dyes
ΔE value | Visual appearance of levelness | Extent of unlevelness |
|---|---|---|
≤0.20 | Excellent levelness | Unlevelness not detectable |
0.21–0.50 | Good levelness | Unlevelness noticeable under close examination |
0.51–1.0 | Poor levelness | Apparent unlevelness |
>1.0 | Bad levelness | Conspicuous unlevelness |
