Java Summary: Given integer values for red, green, and blue, subtract the gray from each value.
Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray).
Given values for red, green, and blue, remove the gray part.
Ex: If the input is:
130 50 130
the output is:
80 0 80
Find the smallest value, and then subtract it from all three values, thus removing the gray

       Scanner input = new Scanner(System.in);

       int red,blue,green,smallest;

       System.out.print("Enter three numbers between 0 and 255 (inclusive): ");

       red =input.nextInt();

       green =input.nextInt();

       blue =input.nextInt();

       if(red <= blue && red <= green){

       smallest = red;

       }

       else if(green <= red && green <= blue){

           smallest = green;

       }

       else{

            smallest = blue;

       }

       System.out.print((red - smallest)+" "+(green - smallest)+" "+(blue - smallest));

}

}

Explanation:

This line declares necessary variables

int red,blue,green,smallest;

This line prompts user for input of 3 numbers

System.out.print("Enter three numbers between 0 and 255 (inclusive): ");

The next three lines gets user inputs

       red =input.nextInt();

       green =input.nextInt();

       blue =input.nextInt();

The following iteration checks for the smallest for red, green, blue

       if(red <= blue && red <= green){

       smallest = red;

       }

       else if(green <= red && green <= blue){

           smallest = green;

       }

       else{

            smallest = blue;

       }

This line prints the required output

       System.out.print((red - smallest)+" "+(green - smallest)+" "+(blue - smallest));
