Custom shaders - PCA dimension: 12 - Color profile: sRGB

SpecimIQ hyperspectral image 1 - Custom shader 1
Color segmentation
If the ΔE 94 color distance between a reconstructed color and a reference color (L*=55.8, a=7.8, b=15.6) is less than 5.0 then the result appears in magenta.
SpecimIQ hyperspectral image 1 - Custom shader 2
Inclusion of infrared information in the color image
If the norm of the vector produced by the 800, 850 and 900nm wavelengths is larger than 0.8 then we apply the following formula: RGB = 0.7*RGB + (0.35, 0.0, 0.0).
