The two on the edges you've seen before. The turquoise and pink are Koigu KPPPM stockinette with garter short row heel. The beige and blue are Lorna's Laces in the color sandridge, using a lace pattern from Kim Salazar's blog.
The new ones are:
Koigu KPM #103 (royal blue) in one of the 4 (or was it 5) stitch rib patterns from Sensational Knitted Socks, with a tubular cast-on, short row heel, kitchenered toe.
Lorna's Laces Shepherd Sock in Cranberry, Vine Lace Socks from Socks Socks Socks, tubular cast-on, short-row heel, and kitchenered toe.
And don't forget the money shot! The color on this one's a little closer, but it's still a bit washed out. The actual color is much darker and not nearly so "hot pink"-ish.
Lastly (for now), some generic stockinetters using Meilenweit Multieffekt #3050.
