Redwood Theme - News and Announcement Heading title colour change

Summary:

We are planning to change from our custom theme to Redwood theme.

Content (required):

When changing to default Redwood theme, our article title headings are not visible. They were light blue colour before. However, there is no option in Redwood to change the title colours. Is there a way to make the title more easy to read i.e. change the colour to white like the tile headings/quick links?
