How to express the result of colour analysis using Lovibond® Tintometer Model F. There are three colour filters red, yellow, blue and neutral. in Hunter colour lab values are expressed as L, a, and b values.How values can be expressed in tintometer. Also , can we analyse solid (seeds, Flour) or liquid samples (juices, oils). please suggest any research article having study on tintometer.
According to theslices number of color i.e. in soy oil 35 yellow and 7 red

Lovibond Tintometer Model F Lab values
The model F is a high specification colorimeter based on the visual comparison of coloured samples with coloured glass filter combinations. A colorimeter is usually a filter based instrument and as such is does not generate precise Lab values. The Lovibond filters are however a well-designed and standardized product and each filter set is graded to conform to a published R,G,B colour identity scale. Their R,G,B colour values are therefore widely taken to be acceptable colour measurements and used in a significant range of industrial applications. Lovibond also sell true spectrophotometers such as the pfx 880 model which can output full spectral curves and CIE L*a*b* colour co-ordinates.
