The 1970 K5 Blazer and Its Factory Color Options

The 1970 model year was the second year of the K5 Blazer’s production, refining what Chevy introduced in 1969. Built directly on the C/K truck chassis, the Blazer shared engines, trims, and—most importantly—its entire paint palette with the full GM truck lineup. Every factory color offered on a 1970 pickup was offered on the Blazer with the exact same name, code, and WA number.

This was also a big year for brighter, more expressive GM paint choices. Colors like turquoise, reds, blues, and greens were common sights on original Blazers, especially when paired with the popular white removable top. For restorers today, having uniform paint codes across multiple truck models gives you a reliable foundation for achieving OEM accuracy.

Restoration Choices for the 1970 Blazer

Even with the original color identified, choosing the right paint system and finish still matters. Some builders prefer period-authentic single stage for a true 1970 look, while others choose basecoat–clearcoat for durability and depth. If you’re unsure which path fits your project, our guide Gloss, Matte or Satin: Matching Finish Type to Your Project Vision walks through how different finishes impact overall appearance.

For a deeper breakdown of application style and long-term maintenance, the article Single Stage vs Basecoat-Clearcoat lays out the pros and cons. Many restorers use the original color formula but upgrade the finish type depending on how the truck will be driven or displayed. The flexibility of the 1970 palette makes it easy to prioritize accuracy or customization without losing the Blazer’s classic identity.

Whether you're restoring a survivor or repainting a full rebuild, the 1970 color lineup remains one of the most balanced in the early Blazer years.
