Squadron has purchased the Scale Colors line of acrylic paints from Jeff Herne (a former FSM editor) and is now producing and selling them through their site. Jeff remains as a consultant. They have a list of 300 current and proposed colors shown on this link.
The product line also includes some figure fleshes and fantasy colors (not shown). Those colors listed on a white background are available now. Those highlighted in tan are phase 2. The plan is to have them available in time for the IPMS USA Nats in August.
I have been using these paints for USN colors for the past 4 years. They are acrylic and are optimized for airbrushing. They perform very well. You can hand touch-up small areas, but hand brushing a whole model is not recommended. They dry quickly to a hard surface. They cleanup with water, windex, or alcohol. They come in 15ml bottles like Vallejo-style. Primers, washes, and clears come in larger (2 oz) bottles.
My 2 cents – I like them.
