Found a pretty close approximation. Nice for a helmet, but wouldn't be a match for the actual paint. On my black matte HJC IS-MAX-BT I used Duplicolor blue metal specks as a base. Topped it with Duplicolor clear Effex, then a Duplicolor clear top coat. Color compliments the bike well. Though, if I had it to do over I'd use a darker blue without specks and get the flake effect by topping with the Effex paint.
Finished my helmet. I'm not thrilled. I messed up the color match.
On the flip face, I got a nasty fingerprint and had to sand and repaint an area. Turns out the extra coat gave it a nice color. With the bucket itself, I apparently didn't work the coats the same and my blue is not as deep. Ugh.
