I am using Triton lite. I can see article titles clearly on the homepage but when I click the article and go to its page I have to highlight the title to see it. I would like to keep the black background and see my text in white.

That would be because you have a black background. Try selecting a lighter color like charcoal > Appearance > Background
Note: Note: A few themes do provide for changing font color in the Blog Title and/or optional Tagline and/or links. In the majority of themes font changes to font families, colors and size in the blog title, tagline, menu, post titles, page titles, categories and tags, widget headings and text, comments, and links cannot be done without CSS editing.
Changing all font families, colors and sizes throughout the whole blog by purchasing an annually renewable Custom Design upgrade and using Typekit Fonts with Staff support is how that’s done > http://en.support.wordpress.com/custom-design/
