Why are brand colours stored as HEX codes?
A brand colour might look like “blue” to us. To a computer, that isn't specific enough. There are thousands of possible blues, and even a small difference in shade can make branded material look inconsistent.
This is where HEX codes come in. A HEX code is a six-character value used to define a precise digital colour. For instance:
Rather than telling a designer or animator to “use the company blue,” the HEX code tells them exactly which blue to use. This becomes particularly useful when producing content across different platforms and formats.
The same brand colour may need to appear in an animated video, a website, social media graphics, digital advertising, presentations, interface or app graphics. Without a defined colour value, different people may select slightly different versions of the colour each time.
Over time, those small differences can make a brand's visual identity less consistent. HEX isn't the only colour system used in production. RGB is also commonly used for digital work, while CMYK is typically used for print. But HEX codes provide a simple, widely recognised way of communicating exact colours in digital environments.
So when a production team asks for your brand colours or brand guidelines, they're not simply asking whether your brand is blue, green or red. They are looking for the specific values that allow that colour to be reproduced consistently.
