This is truly amazing software! I've been using it for about 6 months. Initially I purchased the “Standard” version. However, after using it for a couple of days I decided to upgrade to the “Professional” version. I contacted the company and they let me upgrade for the difference in price. Then they offered to give me a free tutorial session. I gladly accepted their offer. Amazing! The amount of time I save composing my color compositions is substantial. The quality and variety of color choices it provides has become indispensable to my work as a graphic artist. I highly recommend this plug-in.
