Color RGB

ArrayList colors;

BufferedImage bi;

privatedouble colorVariety(){// 0-100

for(int i = 0; i<w; i++){

for(int j = 0; j><h; j++){

int rgb = bi.getRGB(i,j);

if(colors.contains(rgb) ==false){

colors.add(rgb);

}

}

}

return (1.0*colors.size() / (w*h));

}

The above code took a really long time to run with larger images. Since there are only 16581375 different colors, I was thinking of making a boolean[] that long and then mapping each rgb to a boolean and finally counting how many booleans are true.

The problem is, how do I map an rgb to a number from 0-16581374 ?

Tell me if you have any different solutions to the problem also.
