 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.  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.

 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.
