PDF is not showing same color as calendar view when exported

Scheduler ASP.NET MVC
#1

Hi,
PDF is not showing same color as calendar view when exported.
I have used

<input type="button" class="btn btn-primary pull-right" value="Export to PDF" title="Export to PDF"  style="cursor: pointer;margin-right:12px" onclick="scheduler.toPDF('/Generate.ashx','fullcolor')" />

In the calendar page, it is showing

calendarview.png1215×709 35.4 KB

and when exported it shows

calendarpdf.png1600×860 62.2 KB

When we use scheduler.toPDF(‘/Generate.ashx’,‘fullcolor’) it needs to show the same color as the calendar view. But why it is not showing white color text in the pdf?

Thanks in advance.
