theory is that an

object will reflect

more of the light

that matches its

surface color

Demonstration

Because of inaccessibility of micro-Processors

By embodying VBA programming on Excel data sheets

Converts the voltage measurement to RGB value

Compare this value with standard CIE LAB Color Space Coordinates and shows this value using 25 Colors as Standard
