## Description

Refractors are chromium-finish parallel cards with a prismatic rainbow surface that reflects light at multiple angles. The format originated in 1993 with Topps Finest baseball — Topps's then-new chromium printing technology let them apply a thin reflective layer to a base card and price the parallel at a premium. The technique was extended to Topps Chrome (1996), Bowman Chrome (1997), and most subsequent Topps chrome lines.

The canonical refractor is silver/rainbow. Modern releases include color-tiered refractor parallels — Blue Refractor, Gold Refractor, Red Refractor, Orange Refractor, Black Refractor, SuperFractor (1/1) — each typically serial-numbered to a smaller print run. Bowman Chrome Prospect Auto SuperFractors are the most-watched modern refractor format because they combine a 1/1 print run with an on-card autograph of a top prospect.

Refractors should not be confused with parallels from non-Topps brands. Panini's equivalent rainbow finish is called a Prizm (Prizm, Silver Prizm, Gold Prizm, etc.) — the chemistry is similar but the trademarked name differs by manufacturer.

## FAQ

### What's the difference between a refractor and a base chrome card?

The base chrome card has a chromium finish but no rainbow reflection. A refractor adds the rainbow reflective layer, which makes the card visually distinctive when tilted under light. Refractors typically print at a smaller run than the base chrome version.

### Are refractors and Prizms the same thing?

Functionally yes — both are rainbow-reflective parallels. But Refractor is Topps's trademarked terminology (Topps Chrome, Bowman Chrome, Finest, Stadium Club Chrome), while Prizm is Panini's (Panini Prizm, Optic, Select, Mosaic). The chemistry is similar; the brand is different.

### Why are colored refractors typically more valuable than silver?

Colored refractors (Gold, Red, Black, SuperFractor) print at progressively smaller numbered runs — Gold /50, Red /5, SuperFractor 1/1. Scarcity drives the price; the rainbow finish stays roughly the same.
