estimateColorMixture

Estimate color mixtures using weighted average of CIELAB color coordinates

Estimate color mixtures using weighted average of CIELAB color coordinates

estimateColorMixture(x, wt = "pct", backTransform = FALSE)

`x`	data.frame, typically from NASIS containing at least CIE LAB ('L', 'A', 'B') and some kind of weight
`wt`	fractional weights, usually area of hz face
`backTransform`	logical, should the mixed sRGB representation of soil color be transformed to closest Munsell chips? This is performed by aqp::rgb2Munsell default: `FALSE`

A data.frame containing estimated color mixture

See mixMunsell for a more realistic (but slower) simulation of subtractive mixing of pigments.
