This is what it looks like when you attempt to click on a link in Outlook 2013:

The code for Outlook in the email:

<!--[if mso]>
    <v:roundrect xmlns:v="urn:schemas-microsoft-com:vml" xmlns:w="urn:schemas-microsoft-com:office:word" href="https://www.google.com" arcsize="0%" strokecolor="#ffffff" strokeweight="2px" fillcolor="#0077DD" style="height:44px;v-text-anchor:middle;width:120px;">
        <w:anchorlock />
        <center style="color:#fff;font-family:Arial;font-size:16px;font-family:Arial;vertical-align:middle">
            Get Deal <img src="https://i.imgur.com/9dSwLqP.png" style="display:block">
        </center>
    </v:roundrect>
<![endif]-->

I don't know what or how the pink and green colors are appearing, and I wanted to ask if it's possible to prevent those colors from appearing?

Thanks.
