Altering Text Colour using CSS

Site URL: https://www.mirboonorthwinterfest.com.au/

I have successfully altered the body text under Performers using #home3 p {color: white;}, however I am not sure how to change the colour of the heading and 'Read More' link shown above and below this text (hard to see as it morphs into the background). Any advice would be greatly appreciated. 

Hi @sarahprime, this should edit the newsletter title colour:

h2.newsletter-form-header-title {
  color:#ffffff !important;
}

Where are the read more links you want to change the color?

Thanks Ziggy, I will make a note of this (I altered the layout in the end for other reasons). I appreciate your assistance.
