for (double i = 1; i >= 0; i -= 0.01) {
    i = Math.round(i * 100) / 100.0d;
    int alpha = (int) Math.round(i * 255);
    String hex = Integer.toHexString(alpha).toUpperCase();
    if (hex.length() == 1) hex = "0" + hex;
    int percent = (int) (i * 100);
    System.out.println(String.format("%d%% — %s", percent, hex));
}
