is there a possibility to change the color of Zoho-Calendar (like in Zoho-Mail) when I embed it in Zoho-Creator?

I created a page and embed Zoho-Calendar with the following code:

<iframe name='zohoview' height='800px' width='100%' frameborder='0' scrolling='Auto' src='https://calendar.zoho.com/mycalendar#' ></iframe>

Because the blue theme of Zoho-Calendar looks not good with Profesional-Black theme of Zoho-Creator → I want to use grey theme.

Is there also a possibility to hide the Header with Zoho-Logo and User-Menu?
