IMPORTANT - I need feedback

This is important and I need some feedback if someone could be so kind. I was checking my blog on the computer at work today and I noticed I could hardly read it; the colour of the text against the colour of the background made it almost impossible. It looks perfect on my MacBook and I like the colour ways but it's kind of pointless if anyone who wants to read my posts, can't. 

I hope it's just the cheap monitors we use at work; but any comments or emails with your thoughts on this matter would be much appreciated.
