Color Picker, Pattern Picker, Product Builder

I sell two types of wall decals. Solid colored, and printed with solid colors or patterns. I am looking to create a product previewer for customers. For use on desktop, tablet and mobile site views. Here are 2 examples to show the intended implementation of three items: Pre-Designed Decal - Choose colors from available palette, and Unlimited Background Wall Paint Choices (I do not like how you have to select colors in the previewer AND then select them once again to add the item to your cart) [login to view URL] Decal with name/quote - to allow font and word customization (Customer can preview name for name decals, or customize word decals, etc) - drop down menu of font options with preview - when selected it will update the decal previewer - then customer can select colors just as above - and a quick "add to cart" option from the previewer that will add the selected details to the customer's order. Printed Nursery Sets with Color Customization options: [login to view URL] **I am looking for something very similar to this - where some color options are limited, some do not have a limited palette (as in the wall color selector in first link). Patterns are also available to customize the decals. I would like to be able to customize their product selections - for example - you can select the tree only, or the tree and animals - or have a zebra instead of a lion - or have tree style 2 instead of tree style 1 - and the preview will change depending on their selection. I currently am selling on Etsy, and haven't done much with my site which is: [login to view URL] (you can see my options for the jungle decal set) I would need one version where the customer can customize their decals and when they hit submit it emails me their selections (for use with Etsy) Then another that will be used with the shopping cart. I would like to be able to, on my own, after the project is finished, add new designs with the transparent layers for new designs I will have in the future, so back-end capabilities without coding would be helpful also.
