Put the end of one in the flame and see what it does. On Wale Apparatus the 9937 would be Double Mai Tai Pink (boro) so maybe they are all boro? It does not show the rods though, so I can't be sure, but that is a great boro color.
I did a search on the "Trautman Art Glass Rods" and came up with a photo on Etsy with the rods, and it does look like the Double Mai Tai pink.
