I've always been partial to Bruce Snowden's Deep Blue with charcoal
tail...
Blue star with charcoal tail

of this composition is Bruce Snowden
Comments:
Preparation: Add isopropyl alcohol for binding. Cut, round and pumped
stars can be made with this composition, but a typical KClO4/Red
gum/Charcoal/dextrin prime will be necessary. A final layer of sodium
nitrate/sulfur/Charcoal (85/5/10), moistened with NC/acetone lacker (w.
about 3% NC) can be added. This adds yellowish sparks. Mealpowder can be
used instead if the yellow sparks are not desired.
Ammonium perchlorate..............................70
Basic copper carbonate............................10
Red Gum...........................................10
Charcoal..........................................10
Dextrin...........................................+5
These can easily be overpowered by brighter stars, so use by themselves or
with other dim stars.
