In pmur002/colorscience: Color Science Methods and Data

Description

spectra2CRIGAIFSCI Color Rendering Index (CRI), Gamut Area Index (GAI) and full spectrum index (FSCI) from spectra.

Usage

CIETable = get("ciexyz31", envir = environment()), TCS = get("TCSdata", 
envir = environment())) 

Arguments

SPD	light source spd
isoTempLinesTable	Iso temperature lines table
CCT	Correlated Color Temperature (CCT)
CIETable	reference data values
TCS	spectral reflectance data of 14 color test samples for CRI

Value

CRI, GAI and FSCI
