When designers, developers, and branding professionals search for a specific shade that evokes the tranquility of the ocean, the term shark blue colour code often surfaces. This particular hue captures the essence of deep, open water, offering a sophisticated alternative to the overly saturated primary blues. Finding the exact digital representation requires understanding the various colour models used across different mediums.

The Anatomy of Shark Blue

Shark blue is not a single, rigidly defined colour but rather a family of blues inspired by the grey-blue tones of marine life. The most accurate colour code generally falls within the range of a dark, muted cyan. To replicate this specific aesthetic digitally, the RGB model is commonly used, representing colours through Red, Green, and Blue light. The standard reference for a classic shark blue is typically R: 74, G: 144, B: 226.
Decoding the RGB Standard

The RGB value of 74, 144, 226 creates a bright yet serene coastal vibe. In this model, the lower red value prevents the colour from appearing too warm, while the high blue value ensures the cool, watery depth. This balance is what distinguishes shark blue from similar hues like steel blue or cornflower blue, providing a cleaner and more natural ocean feel.
| Model | Code | Usage |
|---|---|---|
| RGB | 74, 144, 226 | Digital Screens |
| Hex | #4A90E2 | Web Design |
| HSL | 210°, 71%, 59% | Art and Illustration |
| CMYK | 67%, 36%, 0%, 11% | Print and Packaging |

Translating Colour to Print
For physical applications such as product packaging, signage, or apparel, the RGB values must be converted to the CMYK colour model. When using the standard shark blue code, the CMYK values are approximately C: 67%, M: 36%, Y: 0%, K: 11%. These percentages ensure the vibrant digital blue maintains its integrity when printed with ink, avoiding a washed-out or muddy result.
Shark Blue in Design Psychology

Beyond the technical specifications, this colour carries significant psychological weight. Blue is universally associated with trust, stability, and calm. The specific tone of shark blue leans toward professionalism and reliability, making it a favourite for corporate branding in the aquatic, tech, and wellness industries. It suggests sophistication without feeling cold, thanks to its subtle grey undertones.
Designers often utilize this shade to create contrast against warmer neutrals like beige or sand. When paired with crisp white space, it evokes a sense of cleanliness and purity reminiscent of wave crests. Alternatively, when combined with darker navy or charcoal, it builds a grounded, executive aesthetic suitable for financial or maritime brands.
Finding the Perfect Shade

Variations of shark blue exist depending on the specific creature or context; for example, the blue of a Great White might be cooler and greyer, while a Blue Shark might appear more vibrant. When searching for the shark blue colour code, it is essential to confirm the context. Most digital asset libraries and design systems standardise the hex code #4A90E2 as the go-to representation for this versatile and enduring colour.
