Optimization results

Chroma value is changing with lighting conditions and can not be easily transformed into a certain color grade.

Color grade borderlines are also changed with hue.

C – Chroma, RC – relative contrast

Before color optimization:

4,02 ct
Cr = 36° P = 43°

Office light: C = 20.24, RC = 0.64
Dialite light: C = 32.51, RC = 0.21

After color optimization:

5,21 ct
C = 48° P = 47.5°

Office light: C = 28.90, RC = 0.54
Dialite light: C = 31.94, RC = 0.18

Then an expert works with optimization results for each shape. It different lighting conditions one can compare stones before and after optimization:

  • by photorealistic images
  • by color metrics
