RadPdfViewer: Input fields can't be read in some dark themes

Open the Demo application >> Interactive Forms example and apply the Office2019Dark theme. You will notice that if the text field enters edit mode, it is difficult to read the input due to black fore color and black backcolor:

Hello, Ken,

Thank you for pointing this out.

Currently, the possible solution that I can suggest is to specify white color for the text field: 

            var provider = new Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.PdfFormatProvider();
            string filePath = @"../../../InteractiveForms.pdf";
            Telerik.Windows.Documents.Fixed.Model.RadFixedDocument doc = provider.Import(File.ReadAllBytes(filePath));

            foreach (RadFixedPage page in doc.Pages)
                foreach (var a in page.Annotations)
                    VariableContentWidget widget = a as VariableContentWidget;
                    if (widget != null)
                        widget.TextProperties.Fill = new Telerik.Windows.Documents.Fixed.Model.ColorSpaces.RgbColor(255, 255, 255);

            this.radPdfViewer1.Document = doc;

I hope this will be suitable for your scenario.
