}This work has been able to replicate Richter's result, and reports here that it is almost certainly instrumental: the Nagel anomaloscope proves to be very sensitive to ambient temperature.

The Nagel anomaloscope: its calibration and recommendations for diagnosis and research
- 2004
Medicine
Rayleigh matches obtained with the Nagel I anomaloscope are sensitive to changes in voltage supply and prism housing temperature, arising largely from thermal effects of the internal light sources.
Psychophysical influences on the validity of anomaloscopic assessments of color vision
- 2008
Psychology
The nature of the perceptual transition into, and out of, a metameric match was found to be less than abrupt, providing ample opportunity for the influence of individual response biases.
Robust colour constancy in red-green dichromats
- 2017
Psychology
The extent of colour constancy for four normal trichromatic observers and seven R-G dichromats when viewing natural scenes under simulated daylight illuminants is estimated to suggest robust colourconstancy mechanisms along daylight locus in R- G dichromacy.
Variability of Rayleigh and Moreland test results using anomaloscope in young adults without color vision disorders
- 2021
Medicine
The observed significant correlations between R1 and M1 suggest that the M1 parameter seems to be the best indicator of blue vision quality, while the Moreland test showed a high MW which did not correspond to the reference range described in the anomaloscope user’s manual.
Comparing Color Vision Testing Using the Farnsworth-Munsell 100-Hue, Ishihara Compatible, and Digital TCV Software
- 2015
Medicine, Computer Science
To compare two traditionally accepted manual tests for detecting congenital color vision deficiency (CCVD) with analogous digital versions, a Bland-Altmann analysis shows that the Online 100-Hue tends to give higher scores than the manuals; however, there are several outliers that lead to a wide range and wide variability.
Peripheral factors affecting human colour perception
- 2016
Biology
For the first time, it was found that natural seasonal changes in the chromatic environment affect the perception of unique yellow; this finding supports the existence of a slow normalisation mechanism, which is governed by changes in achromatic environment.
Effect of lamp voltage on Nagel anomaloscope settings
- 1995
Physics, Engineering
While it has long been known that Nagel anomaloscope matches are influenced by the mains voltage (e.g. Schmidt, 1955) there seem to be no reports of the magnitude of this effect. Because of a recent…

Heredity of Two Types of Normal Colour Vision
- 1967
Physics
The anomaloscope used to diagnose red and green colour blindness and its four or six sub-types is used, and a system of nine equations with the yellow light varying from 574mµ to 603 mµ is built up.
Colour Vision Deficiencies X
- 1991
Medicine
An anomaloscope in which visual angle could be changed to 2°, 6°, 10°, 15° and 20° by using LED's was made and tests on 28 congenital color defects found that shrinking of the matching range was prominent when the visual angle was larger than 10°.
Defective colour vision associated with a missense mutation in the human green visual pigment gene
- 1992
Biology
It is suggested that failure of manifestation occurs when the mutant gene is located at a distal (3′) position among several green opsin genes, which might also predispose to certain X–linked retinal dystrophies.

It is well known that displacements of spectrum lines during a photographic exposure can be caused by changes in the temperature of the dispersing apparatus and of the air in the spectrograph. In the…
