getClosestMunsellChip

Get Approximate Munsell Chip

Description

Non-standard Munsell notation (e.g. '7.9YR 2.7/2.0') can be matched (nearest-neighbor, no interpolation) to the closest color within the munsell sRGB/CIELAB look-up table via getClosestMunsellChip(). A more accurate estimate of sRGB values from non-standard notation can be achieved with the munsellinterpol package.

Usage

getClosestMunsellChip(munsellColor, convertColors = TRUE, ...)

Arguments

`munsellColor`	character vector of strings containing Munsell notation of color, e.g. '10YR 4/3'
`convertColors`	logical, should parsed Munsell colors be converted into sRGB values
`...`	further arguments to `munsell2rgb`

Value

a data.frame when convertColors=TRUE, otherwise character vector

Examples

# convert a non-standard color to closest "chip" in `munsell` look-up table
getClosestMunsellChip('7.9YR 2.7/2.0', convertColors = FALSE)
# convert directly to R color
getClosestMunsellChip('7.9YR 2.7/2.0')
