 You can pass an options object to influence the type of color it produces. The options object accepts the following properties:
 
-```hue``` – Controls the hue of the generated color. You can pass a string representing a color name: ```red```, ```orange```, ```yellow```, ```green```, ```blue```, ```purple```, ```pink``` and ```monochrome``` are currently supported. If you pass a  hexidecimal color string such as ```#00FFFF```, randomColor will extract its hue value and use that to generate colors.

 ```count``` – An integer which specifies the number of colors to generate.
 
-```seed``` - An integer or string which when passed will cause randomColor to return the same color each time.
+```seed``` - An integer or string which, when passed, will cause randomColor to return the same color each time.
 
 ```format``` – A string which specifies the format of the generated color. Possible values are ```rgb```, ```rgba```, ```rgbArray```, ```hsl```, ```hsla```, ```hslArray``` and ```hex``` (default).
