Measurement of cured tobacco leaf colour

Abstract

The Hunterlab and Hilger and Watts colour meters were used to measure cured tobacco leaf colour as an aid in experimental work on cultural and curing problems.
Both gave a satisfactory measure of colour, permitting variations to be interpreted on two-dimensional diagrams.
The leaf condition known as "flatness" was interpreted as comparatively low saturation of hue, and in psychophysical terms as comparatively low purity of dominant wavelength.
