// When ever I am carrying a balance on a credit card, I like to spend nearly
// every penny each month. It's kind of nerve racking, but it's the best way to
// make sure those "bargains" that you just HAD to spend credit on remain
// bargains. (It's amazing how expensive things are when you add in the interest
// you pay!)

// Later I may come back and change the color based on a +/- balance.  But this works for me for now.
// UPDATE: Colors based on thresholds added.  You can tweak the values below:

(function(){
	var colorGreen      = '#080'; // Balances will be this color if they are greater than the theshold below.
	var thresholdYellow = 2000;   // Balances below this threshold will be the color below.
	var colorYellow     = '#990'; // Balances will be this color if they are between the thesholds above and below.
	var thresholdOrange = 1000;   // Balances below this threshold will be the color below.
	var colorOrange     = '#A60'; // Balances will be this color if they are between the thesholds above and below.
	var thresholdRed    =  250;   // Balances below this threshold will be the color below.
	var colorRed        = '#A00'; // This is the color for the rest of the balances.
