Get cell color via Excel Javascript API

In Ms articles they describe how to set the Excel cell color via JavaScript API.

await Excel.run(async (context) => {
    let sheet = context.workbook.worksheets.getActiveWorksheet();
    let usedRange = sheet.getUsedRange();
    let formulaRanges = usedRange.getSpecialCells(Excel.SpecialCellType.formulas);
    formulaRanges.format.fill.color = "pink";

    await context.sync();
});

However, is not really clear, how to get that color. There is any "fill" field when I load the "format"

format: Object
autoIndent: false
columnWidth: 19.5
horizontalAlignment: "Left"
indentLevel: 3
readingOrder: "Context"
rowHeight: 18
shrinkToFit: false
textOrientation: 0
useStandardHeight: true
useStandardWidth: true
verticalAlignment: "Center"
wrapText: false

That is nowhere in documentation samples, as usual in MS poor docs... By testing and guessing I could achieve this:

  let rangeFill = range.format.fill;
  rangaeFill.load(["color"])

  await context.sync();
  console.log("range.format.fill.color", rangeFill.color)

However, the open question remains if there are some conditional formatting applied, how to get the final color? Because this color is one if no conditional formatting applied.
