Since there may be different shades of blue, I think the simple search & replace won't work there.

However, if you use IDE that highlights colors (for example, there Color Highlighter plugin for Sublime Text 3), you can just scan through files in the skins/crisp_white/customer directory and find CSS rules that set the blue color.

I'm not sure if there is a faster way to do this, unfortunately.
