The importance of the latter effect has been disputed by at least one investigator, who attributes to collagen a major role in reflecting blue wavelengths. Methemoglobin is an oxidized hemoglobin in which iron is in perifetica ferric form.

Nevertheless, consistency in observation makes it desirable that artificial light sources be similar to sunlight, since most examining areas are lighted for at least a portion of the day by sunlight.

Blue color can be perceived in a number of situations: If the sample is dark red and becomes bright red on shaking in air, one should perform blood gas analysis on another specimen to confirm arterial hypoxemia. The mechanism of formation is not known, although many of the same toxins that result in the oxidation of deoxyhemoglobin to methemoglobin can also produce sulfhemoglobin.
