   C#

using (FileStream inputStream = new FileStream(Path.GetFullPath("Data/Template.docx"), FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
   // Open the input Word document.
   using (WordDocument document = new WordDocument(inputStream, FormatType.Docx))
   {
       // Iterate through all the styles in the document
       foreach (Style style in document.Styles)
       {
           // Check if the style is a Paragraph style.
           if (style.StyleType == StyleType.ParagraphStyle)
           {
               // Cast the style to WParagraphStyle and modify the text color.
               WParagraphStyle paraStyle = style as WParagraphStyle;
               if (paraStyle != null)
                   paraStyle.CharacterFormat.TextColor = Color.Purple;
           }
           // Check if the style is a Character style.
           else if (style.StyleType == StyleType.CharacterStyle)
           {
               // Cast the style to WCharacterStyle and modify the text color.
               WCharacterStyle charStyle = style as WCharacterStyle;
               if (charStyle != null)
                   charStyle.CharacterFormat.TextColor = Color.Red;
           }
       }
       // Save the modified document.
       using (FileStream outputStream = new FileStream(Path.GetFullPath("Output/Result.docx"), FileMode.Create, FileAccess.Write))
       {
           document.Save(outputStream, FormatType.Docx);
