Rubik Combined Listings on Fluorescent Themes: Stiletto, Eclipse, Cornerstone, Lorenza & Spark (2026)
Fluorescent Design builds themes for brands that want their stores to feel like editorial experiences. Stiletto for luxury fashion. Eclipse for sports. Cornerstone for large home catalogs. Lorenza for boutique retail. Spark for emerging brands finding their feet. Five active themes, 20 presets, 300+ reviews on the Shopify Theme Store. The studio is based in Victoria, BC, Canada, and their client list reads like a museum gala invite: MoMA, Newsweek, Tesla, Yale, The White House. Shopify President Harley Finkelstein has called them “the defacto digital design agency for hip, young retailers and entrepreneurs.” All five themes run Rubik Combined Listings cleanly, without Shopify Plus, without code edits.

About Fluorescent Design
Fluorescent Design Inc. is a Victoria, BC, Canada-based studio building premium Shopify themes and apps. Their portfolio skews editorial and visual: themes that prioritize photography, typography, and brand narrative over dense merchandising widgets. The client list backs the reputation. When MoMA needs an e-commerce presence that matches the curatorial standard, that’s Fluorescent. When Tesla or Yale picks a theme partner, same studio. They also run a 20% commission affiliate program for agencies and influencers who recommend their themes.
Two former Fluorescent themes (Ira and Context) are now retired from the Shopify Theme Store. The five active themes covered here are all maintained with Q1 2026 updates and support the full Online Store 2.0 feature set.
Stiletto + Rubik Combined Listings
Stiletto is Fluorescent’s flagship. $380, 140 reviews (90% positive), version 5.2.2 (February 2026). Ships with 5 presets: Stiletto, Luster, Linen, Glimmer, and Tapestry. Target vertical: luxury fashion. Stiletto is the theme for brands where the product photography does 80% of the selling and the UI exists to stay out of the way while making the photos look incredible.
Where Rubik Combined Listings renders on Stiletto: In the variant section on PDPs and below card images on collection grids. Stiletto’s refined, photography-first aesthetic calls for small image swatches (24px) showing actual product colors rather than abstract circles. Use “Minimal Circles” or “Image Swatch” preset. The “Luster” preset (warm gold tones, editorial spacing) pairs especially well with Rubik’s “Premium” preset for a cohesive luxury feel.
Real use case. A designer handbag brand sells the same silhouette in 6 leathers (Smooth Black, Pebbled Tan, Suede Cognac, Patent Navy, Croc-Embossed Burgundy, Nappa White) as separate products. Each leather has its own photoshoot, its own price point, its own care instructions. Rubik groups them with image swatches showing the leather texture closeup. On Stiletto’s editorial collection grid, one card with 6 tiny leather dots. Customer clicks “Croc-Embossed Burgundy”, lands on that product’s page with the Stiletto layout showcasing the embossed texture in full-resolution hero photography.
Eclipse + Rubik Combined Listings
Eclipse is Fluorescent’s sports and action brand theme. $340, 23 reviews (87% positive), version 5.2.0 (March 2026). Ships with 4 presets: Eclipse, Coastal, Ripple, and Purse. Eclipse’s design has more energy and motion than Stiletto: bolder typography, dynamic section transitions, and a layout that accommodates action photography with wide-angle product shots.
Where Rubik Combined Listings renders on Eclipse: Variant area and collection cards. Eclipse’s dynamic sections have generous padding, so standard-sized swatches (28px) work well. Use “Standard” or “Bold Button” preset. For the “Coastal” preset (lighter, beach-sport aesthetic), color circle swatches in the brand’s accent palette integrate naturally.
Cornerstone + Rubik Combined Listings
Cornerstone is Fluorescent’s large-catalog theme. $360, 42 reviews (88% positive), version 4.2.5 (March 2026). Ships with 5 presets: Cornerstone, Glow, Barista, Botanical, and Origami. Target vertical: home goods brands with deep product lines. Cornerstone handles hundreds of SKUs gracefully, with efficient filtering and dense product grids that don’t sacrifice the editorial feel Fluorescent is known for.
Where Rubik Combined Listings renders on Cornerstone: Dense collection grids and product pages. Use “Compact” preset with small dot swatches (20px to 24px) so cards stay uniform. The “Botanical” preset (nature-inspired, softer palette) pairs well with earth-toned image swatches. The “Barista” preset (coffee/food focused) works nicely with labeled pill swatches showing flavor or scent names.
Real use case. A home fragrance brand sells the same candle jar in 12 scent families as separate products (each scent has unique label art, unique ingredient sourcing, unique burn time). Rubik groups all 12 with image swatches showing each label. Cornerstone’s dense grid shows one candle card with 12 tiny scent dots. Customer clicks “Cedar + Sage”, lands on that scent’s product page with its unique ingredient story and burn time specification.
Lorenza + Rubik Combined Listings
Lorenza is Fluorescent’s editorial boutique theme. $320, 62 reviews (90% positive), version 7.0.4 (February 2026). Ships with 3 presets: Lorenza, Suede, and Tincture. The most magazine-like layout in the Fluorescent lineup. Product pages feel like editorial spreads. Target vertical: curated boutiques, independent designers, niche fashion.
Where Rubik Combined Listings renders on Lorenza: In the editorial product section and on collection cards. Lorenza’s layout gives swatches plenty of breathing room. Use “Premium Pill” or “Premium” preset with medium swatches (28px to 32px). The “Suede” preset (warm, textured) pairs beautifully with image swatches showing fabric or material closeups.
Spark + Rubik Combined Listings
Spark is Fluorescent’s most affordable theme. $200, 37 reviews (92% positive), version 4.0.4 (February 2026). Ships with 3 presets: Spark, Foundation, and Trendsetter. Target vertical: emerging fashion brands and first-time sellers who want a polished look without a $400 theme investment. Spark is the Fluorescent theme for stores that are just getting started but don’t want to look like it.
Where Rubik Combined Listings renders on Spark: Variant section and collection cards. Spark’s clean, accessible layout works with “Standard” or “Compact” preset. Small color circles (24px) keep the emerging-brand aesthetic clean. The “Trendsetter” preset (bolder, more fashion-forward) can handle “Bold Button” swatches with labeled text if the brand has a strong visual identity.

Pairing with Rubik Variant Images
Fluorescent merchants frequently also run Rubik Variant Images for in-product gallery filtering. Full stack: Rubik Combined Listings groups separate products with swatches on collection cards and PDPs. Inside each product, Rubik Variant Images filters the gallery per variant. Two apps, Shadow DOM isolation, no conflict with Fluorescent’s editorial styling. Stiletto’s luxury photography, Lorenza’s magazine layouts, Spark’s clean aesthetic all stay exactly as designed.
“This app makes it super easy to manage images for products that have multiple variations (size and flavor in my case). The support is great as well!”

Frequently asked questions
Does Rubik Combined Listings work on all 5 Fluorescent themes?
Yes. Stiletto, Eclipse, Cornerstone, Lorenza, and Spark are all Online Store 2.0 themes. Rubik drops in via theme app blocks. Ira and Context (retired Fluorescent themes) are no longer on the Theme Store, but if you still run them, Rubik supports those too since they were OS 2.0.
Do I need Shopify Plus?
No. Rubik Combined Listings works on every plan including Basic. Free plan covers 5 groups, Starter $10/mo covers 100. Even Spark ($200 theme) + Rubik free = a working combined listings setup for $200 total with zero monthly fees.
Will Rubik slow down Fluorescent’s editorial page loads?
No. Rubik renders from Shopify metafields with no external API calls. Fluorescent themes are built for visual impact, and Rubik doesn’t add weight to that rendering pipeline.
Which Fluorescent theme is best for a luxury fashion brand?
Stiletto. 140 reviews, 5 presets designed for luxury photography, and the most established theme in Fluorescent’s lineup. Lorenza for editorial boutiques. Spark for emerging brands on a budget. Eclipse if the brand has an action/sport identity.
