You cannot derive the coloring from the actual values in cells, because the table might need to repaint itself before the button was pressed, at which time the colors you want to see are not in accord with the cell value (which, I believe, is the difficulty you're encountering just now).
must paint the table "in the old way" until that button is actually pressed

I also think that you still haven't fully grokked the JTable concepts. At line 9, you're calling model.getValue(row, column), which contains value of the cell to be drawn, but inside this method, this value is available in the value parameter. It's not a mistake, not a big one, but it shows that you still don't "instinctively" know how the table,
model and renderer cooperate to draw a cell. Perhaps you could try to go through the tutorial once more?
It this similar to what you want to achieve?

We both need to be working on identical specs. The specification I've proposed doesn't speak about loading values from the database, but that can be easily changed -
and abstracted away, so that we can still have small, functioning code we can discuss. I cannot meaningfully assist you when you start trying to solve different specification without letting me know what that specification is.

There is two values: minValue and maxValue.The rest is like you wrote.If the cell BETWEEN minValue and maxValue, BLUE, if not, RED.
Lets say min and max are 10 and 50.If the cell is 40, color will be blue, if its 60, RED.
