About RAL 8004
RAL browns are earthy, mature tones used where a refined or natural aesthetic is wanted on industrial or architectural surfaces. The range runs from warm clay (8003) to deep sepia (8014).
RAL codes are administered by RAL gGmbH, a German quality-assurance institute. The RAL Classic library - 213 codes across nine hue families - is the standard for paint, powder-coat, and plastic finishes across Europe, and is used internationally wherever industrial color specification is required. Like every RAL code, RAL 8004 is defined by a physical paint swatch rather than a digital value; the HEX approximation #8E402A is the most commonly-published reference, but physical paint chips are the only authoritative source.
Closest Pantone match
The closest Pantone Solid Coated color to RAL 8004 is 7600 C (#8D3F2B), with a perceptual difference of Delta E 2000 = 0.72. This is a very close match suitable for most print reproduction needs.
Closest RAL Classic neighbors
These RAL codes are perceptually closest to RAL 8004, sorted by Delta E 2000. Codes within the same family differ by Delta E 2-8 typically - siblings rather than duplicates.
Where RAL 8004 is used
RAL 8004 is typically specified in earth-toned industrial finishes, exterior cladding, machinery, and architectural brownfields. Its brown tone makes it appropriate wherever a refined, specialty, or decorative palette is wanted. Before specifying RAL 8004 for a production run, verify the color against a physical RAL swatch under the actual lighting conditions and finish (matte, semi-gloss, gloss) that will be used - the same code looks meaningfully different across substrates.
Frequently asked questions
What is RAL 8004 in HEX?
RAL 8004 (Copper Brown) has a HEX approximation of #8E402A. This is the widely-published mid-range value - RAL is a physical paint standard, and different reference sources vary by 2-5% for the same code. #8E402A is close to every commonly-published reference for RAL 8004.
What is RAL 8004 in RGB?
RAL 8004 converts to RGB 142, 64, 42. Its CMYK print approximation is 0/55/70/44. These values are approximations for design reference - always verify against a physical RAL swatch before production, because paint and ink reflect light very differently.
What Pantone color is closest to RAL 8004?
The closest Pantone Solid Coated match to RAL 8004 is 7600 C (#8D3F2B), with a perceptual difference of Delta E 2000 = 0.72. This is a very close match and is likely suitable for print reproduction.
What RAL color is closest to RAL 8004?
The closest RAL Classic neighbors to RAL 8004 are RAL 8029 (Pearl Copper, Delta E 5.4), RAL 3013 (Tomato Red, Delta E 6.8), RAL 3002 (Carmine Red, Delta E 7.2). RAL codes within the same family typically differ by Delta E 2-8 - close enough to feel like siblings, distinct enough to be visibly different on a physical swatch.
Where is RAL 8004 commonly used?
RAL 8004 is typically used in earth-toned industrial finishes, exterior cladding, machinery, and architectural brownfields. Its brown tone makes it suitable for contexts where this specific hue family carries the intended brand or safety meaning. Verify with a physical swatch under the actual lighting and finish conditions before specifying for a production run.
