So, on Etsy one seller is calling them 11x7mm Bicone Lantern,
they only have 4 colors.

And on eBay this seller is calling them a more generic name,
TRADE CZECH AMBER FIRE POLISHED BOHEMIAN GLASS BEADS so it's harder
to do a search their inventory for other colors.
eBay item number:302212669176

https://www.ebay.com/itm/302212669176?hash=item465d475ef8:g:OOYAAOSwNRdX-vEh

Here it is in cobalt blue. TRADE CZECH COBALT BLUE BOHEMIAN BICONE GLASS BEADS - eBay item number:303514451036

You might want to ask them all if they can get the color you want.

Good luck!
