Homochromous

Thus, it is probable that Magnussen herself photographed the (homochromous) eyes of one pair of twins from the Mechau family, which Georg Wagner had brought to the institute in Dahlem for examination before their deportation to Auschwitz in March 1943, and that she received additional photographs of the (heterochromous) eyse of members of the family in Auschwitz from Liebau.

He obtained in various experiments 124 captures on non-homochromous ground against 68 on homochromous at low illumination.

Fuzeau-Braesch (1985, p. 574) even stated that "gregarious adults are incapable of darkening if transferred onto a black background, as opposed to the solitarious kind that easily bedome homochromous: grouping inhibits homochromy".
