Please give a brief summary of your issue:

We are getting integer value on “public boolean onViewModeColorSelected(int colorMode)” . It return us 3 for Dark, 2 for Light and 1 for None.

Like as we are set view mode using -mPdfViewCtrlTabHostFragment.currentPdfViewCtrlFragment.pdfViewCtrl.pagePresentationMode =PDFViewCtrl.PagePresentationMode.SINGLE_CONT

Same as I tried to set color mode using
mPdfViewCtrlTabHostFragment.currentPdfViewCtrlFragment.pdfViewCtrl.pagePresentationMode = 3
But this made my document black and white or in another view where as 3 is used for dark mode only.

So how can we set light mode or darkmode or none dynamically?

Thanks
Pawan

Since you are using the Viewer Fragment (PdfViewCtrlTabHostFragment2), you can simply call the following to change your color mode to light or dark mode as follows:

                PdfViewCtrlTabHostFragment2 viewerFragment = ...;
                // Set color mode
                PdfViewCtrlSettingsManager.setColorMode(getContext(), PdfViewCtrlSettingsManager.KEY_PREF_COLOR_MODE_NORMAL);
                // Other colors modes...
                // PdfViewCtrlSettingsManager.setColorMode(getContext(), PdfViewCtrlSettingsManager.KEY_PREF_COLOR_MODE_NIGHT);
                // PdfViewCtrlSettingsManager.setColorMode(getContext(), PdfViewCtrlSettingsManager.KEY_PREF_COLOR_MODE_SEPIA);
                viewerFragment.updateColorMode();

Optionally if you need custom color modes, you can further customize the colors using PDFViewCtrl.setColorPostProcessColors(..). You can learn more about this here: PDFTron
