What Are RGB and Hex?

To help you understand why conversion works and when it’s useful:

RGB stands for Red, Green, Blue. It’s an additive colour model used by screens; each component takes a value from 0 to 255.
Hexadecimal (Hex) colour codes are a way to express the same values in base-16. A typical hex code looks like #RRGGBB, where each RR, GG, BB is a two-digit hex number corresponding to red, green, blue.

Use Cases – Why You Might Need to Convert

Here are some common situations where converting RGB to Hex is useful:

Designing websites or themes: CSS often uses hex codes; designers may get colours in RGB (from Photoshop, Sketch, etc.) and need to convert them.
Consistency in branding: Ensuring the same exact colour is used across web pages, graphics, emails.
Developing UI/UX mockups or applications: Matching colours for buttons, backgrounds, margins, etc.
Email templates themes: Many email clients interpret hex more reliably.
Colour matching between tools (e.g. between design tools and code editors).

Frequently Asked Questions (FAQs)

What if the hex code is shorthand, like #F00

Shorthand hex (3 digits) expands to 6 digits by doubling each: so #F00 → #FF0000.

Does every device show colours exactly the same?

Not always. Device display settings, screen type, brightness, and colour profiles affect how colours render. Always test on multiple devices if accuracy is critical.
