Acryla Gouache

I have discovered and purchased aryla gouache by Holbein. It sounds intriguing. It is flat acrylic paint. Since it is flat, other water media such as regular gouache can be used with it. Once dry, it will not blend with other layers. So what excited me about this is that I love to paint on a colored ground and then layer and layer and layer! I'll let you know what it is like when i use it in the next couple of days!
