Develop Opencart color filter plugin

My site, [login to view URL] is under development. It is built on opencart 2.0.2.0, and I use the pavotheme styleshop template [login to view URL] I require a color filter plugin that will make it possible to filter fabrics by colors. I have gone through the OC plugin page, but not find something that works for my need. Find my requirement below Front end (Color Filter Widget): 1. A color swatch filter built on (by extending) OC filter. I need to be able to set filters at the under link tab in product settings 2. Tile design as seen at [login to view URL] NOT list [login to view URL] 3. A selector widget for "AND", "OR" and "NOT" to implement logical AND, OR and NAND, styled as vertical button group [login to view URL] Default will be "AND" 4. AJAX function. Site should not reload on selection 5. A selected filter (color) should be highlighted for visual feedback. Check [login to view URL] 6. A "reset filter" "x", to reset the filter Back end: 1. Filter should be a module, found under Modules. A single instance is OK for the entire site. 2. No core file change. OK to use VQmod or OCmod. 2. Color can be defined by HTML color value i.e [login to view URL] There should be a "Filter value name" field 3. Color filter is associated to products under link tab of product setting. 4. Title of Widget should be configurable. "Shop by colour" can be used as default. Let me know if you need further clarifications
