💡 The color change principle says that color can tell us right away what's going on, without words.
A thermometer doesn't need words to tell us there's a fever - one color is enough.
Our budget can use its own "color code" too, one that shows us our situation in a single glance.
For example:Mark the savings jar
green when it has enough money for the monthly goal,
yellow when it's halfway there,
and red when it's time to be careful and save more.
The moment you see the color, you know the situation right away, without counting the money inside.
When the state of our money "speaks" to us in a clear color, it's much easier to notice it and stay in control.
