 We start in the main script by initializing our variables. ​ we do this to avoid having a variable set to NULL, which is always a good idea.  The two variables we care about are "​var_clrnum,"​ which is color selection, and "​var_color1"​ which is the color itself. ​ If you were wanting to have themes, where each theme has multiple colors that go together, you'd simply add a var_color2, var_color3, etc. in the same manner. ​ Everything else would stay the same, and you'd use the same, single, var_clrnum, to set the color on everything. We start in the main script by initializing our variables. ​ we do this to avoid having a variable set to NULL, which is always a good idea.  The two variables we care about are "​var_clrnum,"​ which is color selection, and "​var_color1"​ which is the color itself. ​ If you were wanting to have themes, where each theme has multiple colors that go together, you'd simply add a var_color2, var_color3, etc. in the same manner. ​ Everything else would stay the same, and you'd use the same, single, var_clrnum, to set the color on everything.
  
-Let's take a closer look at that "​var_color1." ​ This is called an array (or table). ​ What we've done here is set 7 separate values to the same variable, each being a color in hexadecimal format. ​ These seven values are comma-separated,​ and since they'​re strings, each must have a string identifier. ​ In this case, we used apostrophes as string identifiers,​ but you can use quotes if you're one of **those** people :-P.  Just be consistent throughout each array. ​ Don't mix quote identifiers,​ or things can get ugly.+Let's take a closer look at that "​var_color1." ​ This is called an array (or table). ​ What we've done here is set 7 separate values to the same variable, each being a color in hexadecimal format. ​ These seven values are comma-separated,​ and since they'​re strings, each must have a string identifier. ​ In this case, we used apostrophes as string identifiers,​ but you can use quotes if you're one of **those** people :-P.  Just be consistent throughout each array. ​ Don't mix string ​identifiers,​ or things can get ugly.
  
-In an array, we determine which value we want like this:  var_color1[1],​ var_color1[2],​ and so on.  So, all we need to do to change the color is change the number in the brackets. ​ That's where var_clrnum comes in.+Since, in an array, a variable can have multiple values, we determine which value we want like this:  var_color1[1],​ var_color1[2],​ and so on.  So, all we need to do to change the color is change the number in the brackets. ​ That's where var_clrnum comes in.
  
 In the script, we set up a function that acts as a toggle. ​ Each time we call the function, which we'll do via tap action, we increase the value of var_clrnum by one.  When we reach the maximum (the number of entries in our array) value of 7, we simply set it back to 1.  That way, var_clrnum is never a number that does not represent a value in var_color1. In the script, we set up a function that acts as a toggle. ​ Each time we call the function, which we'll do via tap action, we increase the value of var_clrnum by one.  When we reach the maximum (the number of entries in our array) value of 7, we simply set it back to 1.  That way, var_clrnum is never a number that does not represent a value in var_color1.
