What's the difference between dichromatic and hue?
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:

(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.

(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.
Hue
Definition:
(n.) Color or shade of color; tint; dye.
(n.) A predominant shade in a composition of primary colors; a primary color modified by combination with others.
(n.) A shouting or vociferation.
Example Sentences:
(1) A study of colour vision (CV) in 65 patients with multiple sclerosis (MS), (30 patients had had previous optic neuritis) and 51 controls was carried out with Ishihara's pseudoisochromatic plates (I-test), Farnsworth's panel D-15 test (F-test), and Lanthony's desaturated 15-hue test (L-test).
(2) We studied how much blue, green, or red light had to be added to or subtracted from white to obtain veridical hue perception (blue, green, red, or their complementary colours) at various locations in the temporal visual field.
(3) In Experiment 1, newborns differentiated gray from green, from yellow, and from red: For each of these hues they preferred chromatic-and-gray checkerboards over gray squares matched in mean luminance, even though the luminance of the gray checks was varied systematically over a wide range so as to minimize nonchromatic cues.
(4) Data received was converted to Munsell notation for evaluation of the dimensions of color, i.e., Hue, Chroma, and Value, as related to (1) shade differences, (2) thickness of porcelain, and (3) numbers of firings.
(5) Incidentally, it’s the algae that give the coral its colour; and so when it’s ejected, the coral takes on a ghostly white hue, giving rise to the term “bleaching”.
(6) In the remaining four family members normal retinal and cortical responses were recorded under standard conditions and visual fields and colour vision (FM 100 hue) were also normal.
(7) The width of the neutral zone is estimated by the ranges of hues confused with grey.
(8) What they proved, in unambiguous data, was that the photo-op image of Team GB as a changing nation of many hues was not PR fluff but demographic reality.
(9) Munsell's score of the nail samples treated by glycosylation and heating showed increased hue and saturation but reduced lightness.
(10) It is argued that the differential acuity thresholds for hue and the curvilinear age trend may depend upon the coordination of the accommodation and refractive power of the eye, which are affected by differential growth rates of the lens and the axial length of the eye.
(11) The lectin concanavalin-A does not inhibit the binding of 125I-bFGF to HUE cell-surface receptors, whereas it inhibits bFGF binding to BHK-21 cell-surface FGF receptor.
(12) Stimuli were presented either in hue substitution (replacement of white by a chromatic stimulus of matched luminance) or as increments.
(13) The influence of conjunctiva hue on the clinical evaluation of anemia was tested by three educated non-clinicians, trained for such a purpose, in 219 healthy ambulatory subjects.
(14) Spurred by the development of the Farnsworth 100 hue-test, interest was renewed in the 1950s.
(15) It has been observed--on the basis of performed examinations of the color vision by means of the Farnsworth-Munsell's 100-Hue test--that the general numerical index of the faults is increasing proportionally to the period of employment, i.s.
(16) Our results for the FM 100-hue panel are similar to those reported previously by other investigators.
(17) Pairs of test colors of equal hues and apparent lightnesses and 2 degrees subtense were positioned successively within the pair of complex targets and were judged for relative color saturation.
(18) The colour vision of 50 diabetic patients was examined with two screening tests, Standard Pseudoisochromatic Plates part 2 (SPP 2) and Farnsworth Panel D 15 (Panel D 15) test and with two diagnostic tests, Nagel anomaloscope and Farnsworth-Munsell 100-hue test.
(19) There was a great hue and cry and everyone came out – but pretty soon the mullahs sabotaged the consensus and it all went quiet again.
(20) Administration of T did not cause any lizards to change hue, whether their color morph was yellow or orange or lacked the facial pigments altogether.
