DescriptionColor profile
TIFF and JPEG-Images without embedded profile are used in
the third section. However, a wide Gamut Audit Profile is as-
signed here.
The two TIFF and JPEG Image rows within this section must
correspond. They must also correspond with the images from
the second section, as the same profile is applied in both cases
(once embedded, once external).

Color Profile
In the fourth section, two gray value ranges can be seen, which
are composed of a mixture of colors, creating a composite gray.
The first row uses the CieL*a*b* color space, and the second
row uses the RGB (sRGB) color space with the values R=G=B.
Using these gray value ranges, color deviations can be seen very
clearly, because the eye's neutral perception of gray is very
quickly disturbed if the values of the color areas shift in a certain
color direction.
