The guppy is sexually dichromatic, with males being genetically polymorphic for color patches that vary in hue, chroma , reflectivity, size, number, and location on their body.
Significant differences according to species occur with all three parameters: brightness, chroma , and hue.
Humans perceive and classify color using two properties: hue and chroma .
While chroma tends to be faint and fugitive in Bell's early sculptures, a selection of recent works at Jacobson Howard was downright colorful.
High chroma , the intensity of a color, will put more punch in reds and light blues for compacts and sports cars.
We quantified color using three standard descriptors of reflectance spectra: hue, chroma , and intensity of each individual.
Seidl's paintings, with their blunted contours, blending chroma and reticulate brushwork, are all about flux, immanence and the mutating visual field.
We note that, in the model, sex and year effects showed the same patterns of difference as in previous analyses (results not shown): sexual dichromatism in UV reflectance and blue chroma seem independent of age in the barn swallow.
Graphite hits the retina in allusive ways, and in these drawings, broad tonal variety and the use of both white and buff sheets simulate chroma .
Viewers can look underneath and inside the purple forms for a full sensory immersion in chroma and aroma.
