Rainbow Stainless Steel: The PVD Name Explained
What is rainbow stainless steel called?
Rainbow stainless steel is most commonly called “PVD-coated stainless steel” (or simply “PVD rainbow”). You may also see it labeled as “iridescent”, “multicolor”, or “rainbow finish” stainless steel—especially on flatware and kitchen tools. The key term to look for is PVD, which indicates how the color is created and helps distinguish it from painted or dyed finishes.
Why it’s called PVD (and what that means)
PVD stands for Physical Vapor Deposition. It’s a process where a very thin, durable coating is bonded to the surface of stainless steel under controlled conditions. Instead of adding a thick layer of color, PVD changes how light interacts with the surface, which produces that signature rainbow shift—sometimes appearing more blue-purple in one angle and gold-green in another.
Because the underlying material is still stainless steel, product names often combine both terms, such as “18/10 stainless steel with PVD rainbow coating” or “304 stainless with PVD finish.”
Other names you might see on product listings
Retailers and brands don’t always use the exact same wording. If a listing doesn’t mention PVD directly, these labels often refer to the same look:
- Iridescent stainless steel
- Rainbow titanium finish (this usually describes the coating style, not that the item is solid titanium)
- Oil-slick finish (a common nickname for the color-shift effect)
- Multicolor flatware or colorful stainless steel
If durability and care matter, confirming the finish is PVD is helpful, since it’s generally more wear-resistant than basic color plating.
How to shop for rainbow stainless steel with confidence
Look for details like “PVD,” “vacuum coated,” or “titanium-coated” in the description, and check whether the item is dishwasher-safe (many are, but gentler care can preserve the finish longer).
