Simple structure using 3 divs in 1 master div

I only used two of the colour provided: cyan and bright yellow. The others did not make sense at all. I even had to screen shot the design and use a website so I could obtain the colour in the bottom right box. And the text colour in the design was greyish but the light grey colour provided in the styles make the text illegible. Did anyone else find the same issue?

Also I used padding left to indent the text from the left edge. What did other people use?
