RAL 5013 - Cobalt Blue
RAL 5013 (Cobalt Blue) is a RAL Classic color with a HEX approximation of #1E213D, RGB 30, 33, 61, and CMYK 51/46/0/76. It is a blue tone typically used in industrial equipment, machinery casings, architectural metalwork, and infrastructure. Its closest Pantone Solid Coated match is 4146 C (Delta E 1.67), and its closest RAL neighbor is RAL 5003 (Sapphire Blue).
About RAL 5013
RAL blues are heavily used in industry and architecture - the family includes some of the most-recognized RAL codes (5002 Ultramarine, 5010 Gentian, 5015 Sky Blue). Deep navies and steel blues dominate because they suit metalwork and equipment casings.
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 5013 is defined by a physical paint swatch rather than a digital value; the HEX approximation #1E213D 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 5013 is 4146 C (#1B1D36), with a perceptual difference of Delta E 2000 = 1.67. This is a very close match suitable for most print reproduction needs.
Closest RAL Classic neighbors
These RAL codes are perceptually closest to RAL 5013, sorted by Delta E 2000. Codes within the same family differ by Delta E 2-8 typically - siblings rather than duplicates.
Where RAL 5013 is used
RAL 5013 is typically specified in industrial equipment, machinery casings, architectural metalwork, and infrastructure. Its blue tone makes it appropriate wherever a technical, industrial, or nature-referencing palette is wanted. Before specifying RAL 5013 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 5013 in HEX?
RAL 5013 (Cobalt Blue) has a HEX approximation of #1E213D. 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. #1E213D is close to every commonly-published reference for RAL 5013.
What is RAL 5013 in RGB?
RAL 5013 converts to RGB 30, 33, 61. Its CMYK print approximation is 51/46/0/76. 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 5013?
The closest Pantone Solid Coated match to RAL 5013 is 4146 C (#1B1D36), with a perceptual difference of Delta E 2000 = 1.67. This is a very close match and is likely suitable for print reproduction.
What RAL color is closest to RAL 5013?
The closest RAL Classic neighbors to RAL 5013 are RAL 5003 (Sapphire Blue, Delta E 3.0), RAL 5022 (Night Blue, Delta E 4.5), RAL 5002 (Ultramarine Blue, Delta E 5.5). 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 5013 commonly used?
RAL 5013 is typically used in industrial equipment, machinery casings, architectural metalwork, and infrastructure. Its blue 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.
