Also known as / near matches

RAL 5018 Turquoise Blue, a vibrant blue-green, doesn’t have many direct German synonyms, but its essence aligns with hues that evoke a deep, oceanic quality. It’s distinct from its cooler cousin, RAL 5012 Light Blue, and also differs from the softer, greener RAL 6033 Mint Turquoise, which lacks its intensity. While not an exact match, Pantone 328 C offers a similar spirit, capturing a comparable saturation and blue-green balance often associated with this engaging shade.

What it looks like in real life

RAL 5018 Turquoise Blue wraps a space in a deep, contemplative embrace, truly living up to its name. In north-facing light, it reads as a richer, more profound teal, where the blue undertone quietly anchors the green, preventing it from feeling overtly cold. The color deepens, taking on an almost velvety quality that can feel intimate and sophisticated, absorbing the light rather than reflecting it loudly. It never feels stark, but rather, a considered presence. With an LRV of 17, it is a demanding color, requiring thoughtfulness in its application, as it will draw light into itself.

Kompozit’s Wish Upon a Star (0668) stands out as the closest match by a minimal ΔE, also sharing a very similar LRV, indicating a strong overall resemblance in depth and hue. Many of the other brand matches, like Sherwin-Williams Refuge and Behr Blueprint, tend to pull the color into a more muted, grey-blue territory, losing the distinct vibrancy of RAL 5018’s turquoise. The general spread of matches leans towards a cooler, more desaturated blue-grey, highlighting RAL 5018’s unique and more saturated blue-green character.

When to use this color

Great for:

  • This color shines as an accent wall in a sun-drenched living room, where its vibrancy can truly be appreciated.
  • It beautifully elevates cabinetry in a modern kitchen or a powder room, providing a jewel-toned anchor.
  • Consider it for a dedicated study or library, where its depth can foster a sense of focus and calm.

Tricky in:

  • Avoid using this color on all walls in a small room with minimal natural light, as its low LRV can make the space feel heavy and confined.
  • Be cautious in rooms with predominantly artificial cool-toned lighting, as it may lose its green undertone and read as a starker blue.

Painting tips

  • Primer: Given its medium-deep LRV of 17, a white-tinted primer is essential to ensure true color payoff and optimal coverage.
  • Sheen: For walls, a matte or eggshell finish will let this deep color drape beautifully; use a satin for durable cabinets or bathroom walls, and a semi-gloss for trim work to add a subtle contrast.
  • Coats: Expect two coats for full coverage, especially over the recommended tinted primer, ensuring the rich depth of the turquoise is fully realized.
  • Application: With its medium-deep value, even, consistent application is key; brush or roller marks can become noticeable under strong raking light, so spraying may yield the most flawless finish.

Frequently asked questions

Is Turquoise Blue the same as the closest brand match?+
No, while Kompozit's Wish Upon a Star is an extremely close match with a low ΔE, it's not identical. RAL 5018 possesses a slightly more vibrant, less muted turquoise character. Wish Upon a Star often reads as a softer, perhaps ever-so-slightly greyed version of the original, making it a beautiful alternative if a subtle shift in saturation is desired.
What sheen for Turquoise Blue?+
For interior walls, a matte or eggshell sheen allows this rich turquoise to truly drape, offering a soft, sophisticated presence. In high-traffic areas like kitchens or bathrooms, a satin finish provides better durability and cleanability. For trim and doors, a semi-gloss will create a crisp, elegant contrast, emphasizing architectural details beautifully.
Will Turquoise Blue fade on an exterior surface?+
As a vibrant blue-green, RAL 5018 can be susceptible to UV fading over time on exterior surfaces if not protected. It is crucial to use a high-quality exterior paint specifically formulated with advanced UV inhibitors to maintain its rich, saturated hue. Always consult with your paint manufacturer for their best exterior products in deep, vivid colors.
