@hemalp,

Thanks for the sample files.

1). Regarding Aspose.Cells for Excel spreadsheet (XLSX file), please note, a worksheet is composed of cells, so you need to evaluate individual cells of the sheet to get their style/formatting to check background or shading color. You may get the Style of the cell and then evaluate its ForegroundColor to evaluate the color. Please use the Style.ForegroundColor property. It will return cell shading color:
e.g.
Sample code:

var workbook = new Workbook("Book1.xlsx");
var sheet = workbook.Worksheets[0];

//Get the A1 cell
Cell cell = sheet.Cells.GetCell(0, 0);
Style style = cell.GetStyle();

Console.WriteLine(style.ForegroundColor.ToArgb().ToString());

For your information, if the pattern (Style.Pattern) is “Solid” or “None”, the foreground color (set/get) would be the shading color. For all other pattern types, you will use background color of the style.

See the document for your reference:
https://docs.aspose.com/display/cellsnet/Cells+Formatting#CellsFormatting-ColorsandBackgroundPatterns

2). Regarding Aspose.Note for OneNote documents, you may load OneNote document via Document class. Then, access a RichText node whose font and colors are to be retrieved. Now access TextStyle and get text’s font color. See the document for your reference.
https://docs.aspose.com/note/net/working-with-text-styles/

Regarding other file formats and other Aspose for .NET APIs, our respective teams will evaluate and assist you accordingly.

@hemalp,

There is no single property to check color and you have to traverse worksheet cells for it.

@hemalp

For Aspose.PDF, you can determine the page color using below code example in the documentation:

@hemalp

We tested the case using Aspose.PDF for .NET 23.6 and below is the console output that we received in our environment. Would you please make sure to use the latest version of the API and let us know if issue still persists:

Document doc = new Document(dataDir + "ColorText_word.pdf");
foreach (Page page in doc.Pages)
{
    Console.WriteLine($"Page Number : {page.Number} || Color Type : {page.ColorType}");
}

Output

Page Number : 1 || Color Type : Rgb
Page Number : 2 || Color Type : BlackAndWhite
Page Number : 3 || Color Type : BlackAndWhite
Page Number : 4 || Color Type : BlackAndWhite
