            final int level, final int min, final int max) {
        final int diff = min - max;
        final int diffpercent = min - level;
        final float factor = Math.abs((float) diffpercent / (float) diff);

        final int diffa = Color.alpha(col1) - Color.alpha(col2);
        final int diffr = Color.red(col1) - Color.red(col2);
        final int diffg = Color.green(col1) - Color.green(col2);
        final int diffb = Color.blue(col1) - Color.blue(col2);

        final int a = Math.round(Color.alpha(col1) - diffa * factor);
        final int r = Math.round(Color.red(col1) - diffr * factor);
        final int g = Math.round(Color.green(col1) - diffg * factor);
