not based on perception of wave lengths , colours of test objects were
not regarded as important. Instead, in the 10-Second Test, differences
in 1ight energy reflection of test objects were considered more important
since the 10-Second Test was based on cone adaptation. The cones
of the retina are nore stinulated by a colour with higher reflected
energy than a colour with lower reflected energy. For instance, white
refLects more energy than brown and hence, a white object is expected to
be identified faster than a brown object under dim illumination in the
photopic range.
