Input one among the codes to convert it to the opposite one instantly. A successful conversion changes the background color of the page and generates CSS code snippets for quick use.
HEX Input – the primary field accepts values with or without the hash sign. It works for both 3 character long codes. The calculator can handle some typos too, for example when the second digit of a component is an invalid character, not in the hexadecimal range (0-F).
