Did a search for you - try googling hot glue faux wax and you'll have better luck finding them . . .
Colored Hot Melt Glue Sticks (Regular 7/16-inch Diameter) (Glu-Stix) - they look to have every color you're looking for except the teal.
Sealing wax - this place actually has teal (not light teal, though) listed as an available color, but they don't have the pink.
Also, check at your Michael's in the wedding section. The last time I was at mine, they had some colored glue sticks and metal "stamps" for doing wax seals on a small display tucked in near the invitations. I don't remember what colors they had, though.
Oh - I know you don't really want to paint them, but could you use a spray paint to make it go faster if you can't find the color you're looking for?
