I'm currently digging into color calculations/ conversions and also work with DeltaE.
Although the mathematical way might be correct, how can I get a better "human accepted" difference?
Sounds weird, but check out these three examples:
Test one:
Color one:
L 92.05
A -7.57
B 65.76
Color two:
L 85.66
A -6.07
B 65.95
deltaE: 6.56
Test two:
Color one:
L 92.05
A -7.57
B 65.76
Color two:
L 81.81
A -21.06
B 65.86
deltaE: 16.93
Test three:
Color one:
L 92.05
A -7.57
B 65.76
Color two:
L 87.07
A -2.1
B 94.58
deltaE: 29.75
Color one is always the same for comparison. To put it simple: Test 1 is yellow, test 2 is green and test 3 is a darker yellow.
Is there a way to prefer hue over all other values? If I show these three colors a layperson, this person wouldn't say that green is more similar to the other yellow, just because it's a completely different hue.
I know, mathematically it's correct, and yes I also see why "the green" is more similar (I don't know the correct terms to describe it in english). But my endgoal is that a user can input a color and from a limited color palette the three best matching colors will be shown. As I said, green is not a good match for yellow in simple terms.
For testing I used my own deltaE calculator (that's currently not public) and to verify it this one
If you know a better place to ask this, please let me know.
Quick edit:
I know that three formulars for deltaE exists, I tested all three and the 1994 gives me the best result for my original idea and puts green at third place. The calculator I linked uses 1976 and my own calculator originally used 2000.
