Adjusting for Sample Brightness

Adjusting for Sample Brightness
For optimum viewing of color samples, dark
materials require more light, and light materials
less light. When viewing very dark materials, the
sample(s) should be raised closer to the light
source and moved away from the source when
viewing light samples. As a „rule of thumb" very
light materials should be placed at the bottom of
the booth, material of medium lightness should
be raised approximately 13 cm (5 inches) from
the bottom, and very dark materials raised
25.4 cm (10 inches) from the bottom. This is
an approximate light intensity range of 100 to
200 footcandles, covering virtually all viewing
requirements
