My wife likes you initial design. I would like to know a couple of things. First, can you play with the font a little, and maybe mix up the colors a little (very little contrast with that much blue). Also, if I go with your design, can I also get the symbol and words as separate pictures, if I needed to use them separately. Also, would I be able to get a 32 x 32 of the image?
Note about neon colors - they look great in RGB on screen but are often difficult to reproduce in CMYK for print or in PMS colors for silk screening or in thread... so you may want alternatives for different applications.
You may want to google Pantone Matching System Color charts and look at the colors they have as solid coated or uncoated colors on their charts.... those are most commonly used in printing on paper, screen printing or other print techniques... it is used as reference ... It is OKAY to have a version for on line and a different version for in print.
