EDP
Ivory of some sort (I'm partial to honey crunch by vetro, but that's an odd...I'll take any ivory & work with it though
)
Opal Yellow
Copper Green
Black (I'll use vetro or effetre, CIM is fab too, they're all a bit different & fun!)
Clear (gotta be able to encase, or dot & twist, or, or, or...! again, many choices, many possiblities!)
Lichen (yeah, it's an odd, but I love it)
Can I just vote "silver-glass" as a color? My "current" favorites are TN200 (yeah, extinct odd lot), some of Brad's striking-glass frits (sigh...I've gotten samples!), Taxco, Davinci2...I'd say pick any single striking color that suits your fancy & just play with it until you can make it sing...and/or if you're on a hothead, pick a reduction color....they're just so much fun! (or, see if you can luck out & find a "shorts sampler mystery bag" for sale
--add that to some white/clear/black you've got a lot of playtime right there!)
Lauscha Pink (the opaque one)
"Rocky" Rubino by vetrofond--easiest batch ever to strike & lovely plummy color.
I guess that's 10, huh?
I could play with those for a long time....of course, add some silver foil & some frit....
