Link color "Read more" button link text not show in mobile website

In my theme the “Read more” buttons are red with white text.
In coding the “Read more” button text is a link to a website page.

I have set “Links” in the WPthouch admin theme settings manually to: RED

Tab: Corporate identity
Option: Theme color
Option: Links
Option: Pallet
Color: RED

But in the mobile site, the “Read more” button text (Lees meer),
is showing in white color and not in RED ?!

So the (button) link text is not visable in my mobile site,
because the background of the pages is also in white color.

While the (button) link text is actually there on mobile phone.
