title: Total number of possible color combinations
body: <p>I calculated there to be 16,777,216 possible hex color code combinations.</p>
  
  <p>The maximum possible characters that we can have in a single hexadecimal character is 16 and the maximum possible characters a hex color code can contain is 6, and this brought me to my conclusion of 16^6.</p>
  
  <p>Is this correct? If not, please tell me how many possible color combinations there are and how it can be worked out.</p>
