About RAL 5018
RAL teals sit between blue and green - a versatile family that appears both in industrial applications (where it reads as technical and modern) and in decorative settings. RAL 5018 Turquoise and RAL 5021 Water Blue are among the most-recognized codes.
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 5018 is defined by a physical paint swatch rather than a digital value; the HEX approximation #3F888F 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 5018 is 5483 C (#4F868E), with a perceptual difference of Delta E 2000 = 2.89. This is a very close match suitable for most print reproduction needs.
Closest RAL Classic neighbors

Where RAL 5018 is used
RAL 5018 is typically specified in industrial equipment, pool and spa environments, architectural metalwork, and infrastructure. Its teal tone makes it appropriate wherever a technical, industrial, or nature-referencing palette is wanted. Before specifying RAL 5018 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 5018 in HEX?
RAL 5018 (Turquoise Blue) has a HEX approximation of #3F888F. 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. #3F888F is close to every commonly-published reference for RAL 5018.
What is RAL 5018 in RGB?
RAL 5018 converts to RGB 63, 136, 143. Its CMYK print approximation is 56/5/0/44. 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 5018?
The closest Pantone Solid Coated match to RAL 5018 is 5483 C (#4F868E), with a perceptual difference of Delta E 2000 = 2.89. This is a very close match and is likely suitable for print reproduction.
What RAL color is closest to RAL 5018?

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 5018 commonly used?
RAL 5018 is typically used in industrial equipment, pool and spa environments, architectural metalwork, and infrastructure. Its teal 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.
