Frequently Asked Questions
How does the conversion work?
Each pair of hex digits is a base-16 number from 00 to FF, which is 0 to 255 in decimal. #FF8800 is red 255, green 136, blue 0.
What does a 3-digit hex code mean?
It is shorthand where each digit is doubled. #F80 expands to #FF8800. It can only express 4,096 of the 16.7 million possible colours, so it is only used when the colour happens to fit.
What is the 8th digit for?
Alpha, or opacity. #4F46E580 has an alpha of 0x80 = 128, which is 50% opacity — equivalent to rgba(79, 70, 229, 0.5). Every current browser supports it.
Which should I use in CSS?
Either — they are identical to the browser. Hex is more compact and more common in design tools; rgb() is easier to manipulate in code because the components are separate numbers.
Input is processed in your browser and never transmitted. That said, treat any web page as untrusted for live production secrets — rotate anything you paste anywhere.
