The hydrangea flower comes to mind.   Hues of blues and purple perhaps.  Pleasing and relaxing to the eye 
bold yet classic.  I want clients to select my card if it were sitting on a reception desk amongst many others, because it was unique, caught their eye, and they want to try this new amazing skin treatment that people are beginning to talk about. 

Thank you for your help in helping me design my logo for my new business. 
If I need any help in anything further, would you be available to help or do additional designs?  How would I contact you?
