In aqp: Algorithms for Quantitative Pedology

Color Contrast Plot

Description

A simple display of two sets of colors, NCSS color contrast class and CIE delta-E00.

Usage

colorContrastPlot(
  m1,
  m2,
  col.cex = 1,
  col.font = 2,
  d.cex = 1,
  cc.font = 3,
  dE00.font = 1,
  labels = c("m1", "m2"),
  label.cex = 1,
  label.font = 1,
  printMetrics = TRUE,
  ...
)

Arguments

m1	first set of Munsell colors for comparison (e.g. '5YR 3/2')
m2	second set of Munsell colors for comparison
col.cex	scaling factor for color labels
col.font	font for color labels
d.cex	contrast for contrast metric labels
cc.font	font for contrast class
dE00.font	font for delta-E00
labels	labels for compared colors, vector length 2
label.cex	scaling factor for labels
label.font	font for labels
printMetrics	logical, print metrics between color swatches
...	further arguments to colorspace::swatchplot

Note

This function requires the farver package for calculation of CIE delta-E00.

Examples

# keep examples from using more than 2 cores
data.table::setDTthreads(Sys.getenv("OMP_THREAD_LIMIT", unset = 2))

# two sets of colors to compare
m1 <- c('10YR 6/3', '7.5YR 3/3', '10YR 2/2', '7.5YR 3/4')
m2 <- c('5YR 3/4', '7.5YR 4/4', '2.5YR 2/2', '7.5YR 6/3')

# contrast metrics
colorContrast(m1, m2)

# graphical display
colorContrastPlot(m1, m2)
