What's the difference between dichromatic and dichromatism?
Dichromatic
Definition:
(a.) Having or exhibiting two colors.
(a.) Having two color varieties, or two phases differing in color, independently of age or sex, as in certain birds and insects.
Example Sentences:
(1) Although the lens did not alter stereopsis, it did produce severe color discrimination losses for normal and dichromatic subjects.
(2) Furthermore, it was suggested that the patterns of the panel D-15 test differ by the convergence points among dichromats even of the same type.
(3) Discrimination tests reveal that these squirrels have dichromatic colour vision with spectral neutral points centered at 507.5 nm.
(4) The results indicate that dichromatic and trichromatic monkeys differ only trivially on tests where performance is based on the contributions of non-opponent mechanisms, that the contribution of spectrally opponent mechanisms to the "brightness signal" is very similar in trichromatic and dichromatic monkeys, and that in increment-threshold discriminations where there are both chromaticity and luminance cues some test wavelengths yield superior performance for trichromats while others appear to favor the dichromat.
(5) Both sets of data for the two types of dichromat satisfy linearity properties.
(6) Spectral characteristics of X-linked Dichromats (13 protanopes, 20 deuteranopes) were studied with spectral ERG.
(7) The results imply that newborns have some, albeit limited, ability to discriminate chromatic from achromatic stimuli and hence, that they are at least dichromats.
(8) Measurements were carried out using noninvasive techniques: quantitative computer tomography and dual photon absorptiometry (mono- and dichromatic).
(9) Many errors were due to the small number of protanopes averaged and inability to distinguish trichromats from dichromats.
(10) If dichromats lack one of the normal pigments then the upset of these matches monitors the change in spectral sensitivity of a single mechanism.3.
(11) Then, the chromaticity-coordinates of each color cap were calculated using the spectral distribution of standard illuminant C. The theoretical patterns of the panel D-15 test for dichromats were obtained based on the confusion lines.
(12) Two of the four observers had normal trichromatic colour vision; the other two were dichromats (protanopes).
(13) Thus the color vision in these animals is dichromatic.
(14) Spectrophotometric analysis of this blue dye at different concentrations and with or without heparin showed that the reddish hues are due to dichromatism and not metachromasia.
(15) The results suggest that the adult expression of dichromatic color vision does not depend on color experience during the first 4 months of life.
(16) Collectively, these and previous results imply that although newborns have at least dichromatic color vision, they possess relatively poor chromatic-achromatic discrimination in two spectral regions - in the short-wavelengths (including stimuli of 470-480 nm) and in the mid-wavelengths (including 565 nm).
(17) (3)-(8) are consistent and allow the calculation of a maximum optical density for those pigments which underlie the dichromats' long-wave mechanism.
(18) An intense background also changes the relative spectral sensitivity of the dichromats.
(19) Temporal properties of the short-wavelength cone mechanism of the California ground squirrel (Spermophilus beecheyi), a dichromat, were explored with single light pulses and pulse trains.
(20) Sampling was from the femoral artery through a dichromatic cuvette densitometer.

(n.) The state of being dichromatic.
