Same 10 frames, 30 colourways and 56 lenses underneath — same persistence rules, same imagery. What changes is what the page is for. Click through each, then tell me which one feels like eyewear and which parts to steal from the others.
A real product page. If a retailer asked “what would this look like on my site”, this is the literal answer.
Your window idea, taken literally. The product sits in a lit arch cut into a dark room, and the room takes its colour from the lens you pick.
Split editorial. The left half floods with the frame’s own measured colour, so the page restyles itself as you move through the range.
Placeholder copy. Product names (Ashcroft, Bellamy…), prices and review counts are invented so the pages read like a shop — swap them for the real catalogue. Colour names and swatches are measured from the renders: the lens region is found by diffing each variant against the clear lens, and the frame colour is the median of what's left. The original control-panel build is still at tool.html for comparison.
