Hex colors are a popular way to create various colors in hexadecimal format (a hex triplet). They are often used in CSS and HTML codes to quickly change the color of a webpage or web asset. Hex colors can help with color identification and could be useful for designers.
Hex colors are easy to identify and use when you have multiple colors on screen. It is also easier for designers since they can copy and paste the hex code instead of having to remember RGB or CMYK values
It is always easier to understand a hex color than a traditional RGB digital color. And the use of hex colors in the digital world has spread across platforms like websites, apps, and e-commerce stores.
