plotColorMixture: Visualize Spectral Mixing of Munsell Colors

In aqp: Algorithms for Quantitative Pedology

Visualize Spectral Mixing of Munsell Colors

Description

Lattice visualization demonstrating subtractive mixtures of colors in Munsell notation and associated spectra.

Usage

plotColorMixture(
  x,
  w = rep(1, times = length(x))/length(x),
  mixingMethod = c("exact", "reference"),
  n = 1,
  swatch.cex = 1.5,
  label.cex = 0.85,
  showMixedSpec = FALSE,
  overlapFix = TRUE
)

Arguments

x	vector of colors in Munsell notation, should not contain duplicates
w	vector of weights, can sum to any number
mixingMethod	approach used to simulate a mixture: exact: simulate a subtractive mixture of pigments, color conversion via CIE1931 color-matching functions (see mixMunsell()) reference : simulate a subtractive mixture of pigments, selecting n closest reference spectra, requires gower package
n	number of closest mixture candidates when mixingMethod = 'reference' (see mixMunsell()), results can be hard to interpret when n > 2
swatch.cex	scaling factor for color swatch rectangle width and height, relative to label.cex, typically between 1 and 3
label.cex	scaling factor for swatch labels
showMixedSpec	show weighted geometric mean (mixed) spectra as dotted line (only when mixingMethod = 'reference')
overlapFix	attempt to "fix" overlapping chip labels via fixOverlap(), using method = 'E'

Details

If present, names attribute of x is used for the figure legend. See the expanded tutorial for examples.

Value
