How to change font color in product header bar?

I have current version of Zen Cart. Model, item name, and price fonts are shown in blue and product image font is white. The white font color shows up very well with the green header bar, but the blue font color is almost a blur. The blue color means these three items can each be sorted. I just need to know where to go as I have tried changing stylesheets in my template directory and refreshing it before I view it, but nothing changes. I have shutdown computer for over five minutes and still nothing.
Thank you in advance for your help and suggestions.

I answered this in your other post. The rule I suggested works on a stock Zencart installation if you add it to the end of the stylesheet. If you've added a custom template or a mod that affects the product listing, we'll need to see the site.
