How to recolor text in selected cells?

Question

Google Apps Script

Hello.
There is a google spreadsheet. It contains several cells. How to recolor the text in these selected cells?
This is how we recolor when the cells are known.

var spreadsheet = SpreadsheetApp.getActive();
  spreadsheet.getRangeList(['A4', 'A8', 'A13', 'A19', 'A23']).activate()
  .setFontColor('#ff0000');

And if they are only selected. How then to recolor the text in these selected cells? Please help.

Here is a code that will help:

function rePaint() {  
  SpreadsheetApp.getActive().getActiveRangeList().setBackground('#ff9900');
};

Answer 2

Wrote a function. But it doesn't color the text. Where is the mistake?

function ColorRange(){
  const sheet1 = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Прейскурант товаров");
  //sheet1.getActiveRange().setFontColor('#00ff00');
  sheet1.getActive().getActiveRangeList().setFontColor('#00ff00');
};

This one worked

function ColorRange(){
  const sheet1 = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Прейскурант товаров");
   sheet1.getActiveRangeList().setFontColor('#00ff00');
};
