exchanging colors in css

Many of the links on my website show up as red (#ea2e25). I want to change them to blue (#0000ff). I can do this by scouring my css style sheet and changing #ea2e25 to #0000ff each time I see it. This is a lot of work. I want to make some sort of rule in my custom css that would do this automatically. I have searched the forum but was only able to find out how to change ALL links (which included things like my menu items that are gray). Is there an easy way to make the output of each link #0000ff instead of #ea2e25?
