Line 59:

-- this function returns the string "#RRGGBB" with approximate RGB value for a complementary color (reflection) to a color, defined as a wavelength passed as a first argument

-- The following formula is used for the complimentary color: {0xFF - RR, 0xFF - (RR + BB)/2, 0xFF - BB}

-- local wavelength = tonumber(frame.args[1])

-- nm2RGB(wavelength)

local result='#' .. string.format("%.2X%.2X%.2X", 255*(1-redvalue), 255*(1-greenvalue), 255*(1-bluevalue))

-- local result='#' .. string.format("%.2X%.2X%.2X", 255*(1-redvalue), 255*(1-greenvalue), 255*(1-bluevalue))

local wavelength = ceil(tonumber(frame.args[1])/10)*10

-- local result='#' .. string.format("%.2X%.2X%.2X", 255*(1-redvalue), 255*(1-(redvalue+bluevalue)/2), 255*(1-bluevalue))

nm2RGB(wavelength)

local result='#' .. string.format("%.2X%.2X%.2X", 255*(1-redvalue), 255*(1-greenvalue), 255*(1-bluevalue))
