Colour Vision Properties For Peel of Mango's Fruit: An Approach to Objective of Total Pigments Assessment: RGB, CMY And Total Pigments Relations Mathematical Guide

摘要

This study experimented the peel of fourteen cultivars were healthy ripe of Mango fruits (Mangifera indica L.) selected after picking from Mango Spp. namely Taimour [Ta], Dabsha [Da], Aromanis [Ar], Zebda [Ze], Fagri Kelan [Fa], Alphonse [Al], Bulbek heart [Bu], Hindi-Sinnara [Hi], Compania [Co], Langra [La], Mestikawi [Me], Ewais [Ew], Montakhab El Kanater [Mo] and Mabroka [Ma] under two color space tests (RGB: Red, Green and Blue) and (CMY: Cyan, Magenta and Yellow) utilizing digital color photographs as tool for obtainment the natural color information for each cultivar as a non-destructive analyses then the result linked with total pigment estimation as a destructive analyses. Our study was suggested the concentration (%) of structure pigments as well as some Pigment Index formula opposite some Color Space Index. To study and determine precisely the mathematical relations between concentration (%) of structure pigments and the digital visual color for purpose the interpretations and illustrations of the structure pigments induction on the color space elements. The result indicated to strong numeric correlation between total pigment data and color space data which the color space tests approach to evaluation the total pigment.
