Decimal is base 10 — the everyday notation, and the one every other base is usually being translated back into. Hex is base 16 and maps exactly four bits per digit, which is why one byte is always two hex digits and why colours, memory addresses and hashes are written this way. As a worked example, 255 equals 255 in decimal and therefore FF in hexadecimal.
