This paper outlines the key differences between ANSI 70 and RAL 7035, two of the most common industrial gray standards used for electrical enclosures, machinery, and outdoor infrastructure. Executive Summary
While both are "Light Grays," they belong to different standardization systems. ANSI 70 is the North American standard (often referred to as "Sky Gray" or Munsell Gray), whereas RAL 7035 is the European standard ("Light Grey") that has become a global industrial benchmark. ANSI 70 Gray RAL 7035 Light Grey Origin American National Standards Institute (USA) Reichsausschuß für Lieferbedingungen (Germany) Visual Tone Medium-light neutral gray; "flat" look Very pale, cool silvery-gray; almost white LRV (Light Reflectance) ~35% – 40% (Medium) ~57% (High/Bright) Primary Use US utilities, switchgear, transformers Global electronics, data centers, enclosures HEX Code Approx. #838988 Approx. #C5C7C4 1. ANSI 70: The North American Utility Standard
ANSI 70 (defined under ANSI Z55.1) is the legacy standard for heavy industrial equipment in the United States.
Color Profile: It is a "controlled" neutral gray with low chroma, meaning it does not lean heavily toward blue or yellow.
Applications: It is predominantly seen on outdoor electrical equipment, such as pole-mounted transformers, substation switchgear, and heavy industrial frames.
Durability: Typically formulated as a TGIC Polyester powder coating for high UV resistance and outdoor exposure. 2. RAL 7035: The Global Modern Standard
RAL 7035 is part of the RAL Classic collection and is arguably the most used color in modern industrial design worldwide. RAL 7035 Light Grey Paint | Touch-Up & Maintenance
Note on terminology: In the industrial design and enclosures industry, the most common ANSI standard for color matching is ANSI 61 (Gray). ANSI 70 is often colloquially used or confused with light grays, but the correct ANSI standard for "Light Gray" is typically ANSI 70 (which is darker than ANSI 61? Actually, let's correct this upfront: NEMA/ANSI standards for enclosures use ANSI 61 (Gray), ANSI 49 (Medium Gray), and occasionally ANSI 70 (Light Gray). However, major brands like Rittal and Hoffman standardize on ANSI 61 (dark gray) for industrial controls. ANSI 70 is a light gray used in telecom. For the purpose of this comparison against RAL 7035 (Light Gray), we will compare ANSI 70 (Light Gray) vs RAL 7035 (Light Gray).)
Q: Can I paint over ANSI 70 with RAL 7035? A: Yes, but use a high-adhesion primer. The high gloss of ANSI 70 must be scuffed (sandpapered) first.
Q: Which is lighter in color? A: ANSI 70 is slightly lighter (higher LRV) and appears much lighter due to its gloss reflection. ansi 70 vs ral 7035
Q: Which is better for outdoor use? A: ANSI 70 (High gloss) offers superior UV resistance and moisture barrier compared to standard matte RAL 7035.
Q: Does Dell/HP use ANSI 70 or RAL 7035 for servers? A: Dell and HP server chassis are usually a custom gray, but their racks are typically ANSI 70 in the US and RAL 7035 in EMEA.
John insisted that they should go with ANSI 70, a specification he had used for years without any issues. Maria, on the other hand, was adamant that RAL 7035 was the way to go, citing its superior color consistency and durability.
As they sat in the conference room, surrounded by swatches of different colors and catalogs from various suppliers, John began to recount a story from his previous job. "I remember when I worked at XYZ Corporation, we used ANSI 70 for all our equipment enclosures. It was a standard issue, and our maintenance team never complained about the color fades or mismatches."
Maria listened attentively but countered with her own experience. "That may have worked for you in the past, John, but I've worked with RAL 7035 on several projects, and the results have been outstanding. The color is more vibrant, and it holds up much better to environmental factors like UV exposure and extreme temperatures."
As they continued to debate, their colleagues, Tom from engineering and Emily from design, walked into the conference room, curious about the commotion. Tom, a fan of technical specifications, jumped into the discussion, pointing out that ANSI 70 was equivalent to a specific range of colors defined by the American National Standards Institute, whereas RAL 7035 was a European standard that might not be directly compatible.
Emily, with her design background, chimed in, "But have we considered the aesthetic implications? ANSI 70 might be a more neutral gray, while RAL 7035 has a slightly blue undertone that might clash with our brand colors."
As the discussion grew more complex, John and Maria decided to put their differences to a test. They agreed to order a small batch of enclosures in both ANSI 70 and RAL 7035 and conduct a side-by-side comparison.
A few weeks later, they gathered in the plant's storage yard, where the enclosures were on display. The verdict was almost immediate: while both colors looked good, the RAL 7035 enclosures had a noticeably crisper, more vibrant appearance that seemed to match the company's brand guidelines more closely.

John turned to Maria and smiled. "I think you've convinced me. RAL 7035 it is." Maria smiled back, and the two of them shook hands, marking the beginning of a beautiful collaboration.
From that day forward, the company standardized on RAL 7035 for all equipment enclosures, ensuring a consistent and durable color appearance that pleased both the quality control and design teams. As for John and Maria, they became great allies, often reminiscing about the "Great Color Debate" that brought them closer together and improved their company's processes.
Choosing between ANSI 70 and RAL 7035 is a common task in industrial design, specifically for electrical enclosures, machinery, and outdoor infrastructure. While both are "light greys," they belong to different standardized systems and have distinct visual characteristics and regional dominance. Core Differences at a Glance ANSI 70 (Light Grey) RAL 7035 (Light Grey) System American National Standards Institute RAL Classic (German/European) Common Name Sky Grey / Munsell Grey Light Grey / Lichtgrau Visual Tone Medium-light, neutral, "industrial" grey Very light, cooler, silvery-grey Light Reflectance Typically lower (~20–40% depending on mix) High (LRV ~57–58) Primary Region North America Europe and International What is ANSI 70?
ANSI 70 is the standard "Light Grey" used extensively in North American industrial settings. It was originally defined by the American National Standards Institute and is often cross-referenced with the Munsell color system (typically Munsell 5BG 7.0/0.4).
Appearance: It is a neutral, medium-light grey. Unlike RAL 7035, it doesn't lean as heavily into blue or silver tones, appearing more like a "solid" grey used for heavy machinery and utility boxes.
Applications: It is the default for high-voltage electrical equipment, switchgear, and transformers in the U.S..
Durability: Most ANSI 70 coatings, such as those from Diamond Vogel, are TGIC Polyesters designed for extreme outdoor durability and UV resistance. What is RAL 7035?
RAL 7035, or "Light Grey," is perhaps the most widely used industrial color in the world. Originating in Germany, it has become the global benchmark for telecommunications, electronics, and interior enclosures.
Appearance: It is significantly lighter and "cleaner" than ANSI 70. It has a subtle cool undertone that gives it a modern, professional look. RAL 7035: Cheaper globally
Light Reflectance (LRV): With an LRV of approximately 57–58, it is highly reflective. This makes it ideal for indoor environments like data centers or laboratories where it helps maximize ambient light.
Versatility: It is available in various finishes, from the Prism Powder high-gloss versions to matte and textured "wrinkle" finishes often seen on computer server racks. Detailed Comparison: Visuals and Performance 1. Color Depth and Tint
If you place them side-by-side, ANSI 70 is darker than RAL 7035. ANSI 70 looks like the color of a rainy sky or a traditional battleship, while RAL 7035 looks like "off-white" or light concrete. RAL 7035 is preferred for modern aesthetics, whereas ANSI 70 is the "workhorse" color for utility and power infrastructure. 2. Global vs. Regional Standardization
If your project is bound for Europe or Asia, RAL 7035 is the safer bet for color matching, as the RAL system is the international language of powder coating. If you are working on a domestic U.S. power grid project, ANSI 70 is likely the specification requirement. 3. Maintenance and Touch-Up
Because RAL 7035 is so light, it tends to show dirt, grease, and scuffs more easily than the slightly darker ANSI 70. However, because RAL 7035 is globally ubiquitous, finding touch-up pens and aerosols is generally easier. For example, brands like Aouracryl and Soudal offer easy-to-use RAL 7035 spray cans for field repairs. ANSI 70 Gray - Diamond Vogel
When placed side-by-side, the differences between ANSI 70 and RAL 7035 become apparent:
