What Happened to Scalecoat Keystone Black?
If you've searched for Scalecoat Keystone Black, chances are you've found old forum discussions, discontinued paint lists, or longtime model railroaders wondering what happened to one of Scalecoat's most respected black paints.
Over the years, several rumors circulated online. Some believed Keystone Black had simply disappeared. Others thought it had been renamed to another railroad-specific color. The truth is actually much simpler—and much better for modelers.
The Original Keystone Black
Keystone Black was one of the original Scalecoat paint colors, originally cataloged as Color No. 4 during the early years of the Scalecoat product line. It developed a loyal following, particularly among Pennsylvania Railroad modelers, because it produced a rich, warm black finish that many considered ideal for locomotive details and other applications.
By the early 2000s, rumors began circulating that Keystone Black was being discontinued. Hobbyists speculated that it had been renamed or replaced by another railroad-specific black. While those discussions have become part of Scalecoat history, the actual reason for its discontinuation was much less dramatic.
Why Keystone Black Was Discontinued
Keystone Black was not discontinued because of quality, demand, or performance.
It was discontinued because it duplicated another color already in the Scalecoat lineup.
As the product line evolved and additional colors were introduced, Scalecoat added Detail Black. Rather than maintaining two different stock numbers for paints using the same color formula, Keystone Black was eventually retired to simplify the catalog.
In other words:
- Keystone Black and Detail Black share the same color formula.
- The discontinuation eliminated duplicate colors from the product line.
- The color itself never disappeared.
Today's Equivalent: Scalecoat Detail Black
If you're looking for the original Keystone Black color today, you're in luck.
The modern equivalent is Scalecoat Detail Black.
Available in both paint systems:
- Scalecoat I Detail Black (SMZ1112) – formulated for brass, white metal, and other metal models.
- Scalecoat II Detail Black (SMZ2112) – formulated specifically for styrene, plastics, resin, and most modern model kits.
Not Every Black Paint Is the Same
Experienced modelers know that "black" is not a single color.
Different manufacturers formulate black paints with varying undertones, gloss levels, opacity, and pigment blends. Some blacks lean cool or blue, while others have warmer characteristics. These subtle differences become especially noticeable on steam locomotives, diesel details, freight car underframes, and weathered equipment.
Scalecoat Detail Black continues the same proven color formula that originally made Keystone Black so popular among hobbyists.
Preserving Scalecoat History
Since acquiring the Scalecoat product line, we've been working to preserve not only the paints themselves, but also the history behind them.
Many discontinued Scalecoat colors have developed almost mythical status over the decades, with stories passed between model railroaders and online forums. Whenever possible, we're researching original records, production notes, and historical documentation to separate fact from speculation.
Keystone Black is one of those stories.
While the original catalog number has been retired, the color itself lives on today as Scalecoat Detail Black, allowing a new generation of modelers to continue using the same trusted color that has been part of the Scalecoat legacy for decades.
