Hi, here are some variations, and I would love to have your feedback. I'm not quite sure what you meant by a slight purple background? Would you like me to replace the white background here with a light purple color? Even though you said you liked the type, I've also tried a custom wordmark (not a font) to give you an option. I also made a free-flowing beanstalk as you asked, trying it alone and encompassed by a circle (which makes a sort of yin yang shape). Of course, colors can be altered. If you're not seeing the right colors, sometimes it can be helpful to provide examples -- color descriptions can be so subjective. There are several color scheme tools on the web, such as
http://colourlovers.com or
http://colorschemedesigner.com/ that could help. Another way to help guide us on color is to find photographs (try google images or flickr) that include colors that you like. We can grab colors right out of a photo with our design software. Thanks so much!
