Experimental RGB and CIE L*a*b* colour space analysis and comparison for fruits and vegetables


Colour indicates the freshness and dryness of fruits and vegetables. Many colour space are available to measure the approximate colour value of natural food items. This experiment deals with comparison of colour reproduce by RGB colour space value and CIE L*a*b* colour space value. Fruits and vegetables sample of different colour shades where selected and their high definition photos were taken and converted into RGB colour space and CIE L*a*b* colour space using MATLAB 2015a V2.1 and reproducing the colour in Adobe Photoshop Creative Studio 6 V13.0.1. The colour reproduced shows that colour obtain by RGB colour value appears more balanced in hue and saturation as compare to those colour obtain by CIE L*a*b* colour space value. But it is more convenient to use CIE L*a*b* colour space because its colour coordinates can explain the level of saturation and hue in numerical way.
