Text Colour Variations

Hi folks,

I am trying to replicate a colour difference in text from one section to the next, though inverting the black and white text against green and pink backgrounds. In the section 'Complete Accent Kit', you can see that the white text and white underline has converted on the green, and the black text and black underline works on the pink. However, in trying to invert this on the 'Vocal Mastery' section, the Heading and Paragraph colours aren't co-ordinating with the colours I want them to be (pink= black text, green= white text). I've gone in and tried changing all variations of text colours, but it won't do what I need as it did in the 'Complete Accent Kit' section.

When I try to make all the text one colour for one half of the section, it adjust the other side too so it's invisible. But with the same colour settings (inverted) in the other section... it simply did what I wanted! Very confused.

Help!
