Recommendations For Color Assessment Environments
-
Comply with colour viewing / measuring geometry 0°/45° or vice versa. If necessary, use sample holders to provide the correct geometry.
-
Put samples close together.
-
If possible, colour samples should have the same dimensions
-
Ambient conditions should be as neutral as possible. Try to avoid ambient light.
-
For very dark substrates a light box with matte-black interior lining can be used to reduce the contrast. Otherwise the colour viewing booths must be neutral gray (Munsell N7).
-
Obersers should wear neutral clothing to avoid reflections from their clothes.
-
Only the viewing samples should be in the viewing booth at the time of assessment to avoid colour contamination from other samples
-
The observer should be tested for normal colour vision and should have experience in visual color evaluations.
-
Give your eyes time to adapt to the ambient conditions and do not look at any strong colours directly before the assessment
-
If you own standards and guidlines are used, inform all parties who are involved in the colour assessment procedure and insepct conformance
-
Use several different illuminants to detect metamerism
-
If the substrates are fluorescent, UV radiation must be included in sources used for colour assessments
-
Replace your fluorescent lamps regularly according to the manufacturer’s instructions.
