Some lab scanners use trichromatic light or bandpass filters, but they are not precise enough bandwidths so some of the green layer is recorded as blue and red, and some of the red and blue is read as green. This can cause trouble interpreting red/magentas, orange/yellows, and cyan/blues. The conversion can then render a golden/amber colored boat as pale yellow, turquoise water as faded cyan, a baby blue sky as pastel purple, forest green foliage as khaki/brown, etc.
