[jQuery] Replacing colors

[jQuery] Replacing colors


Hi,
I am wondering if it is possible to replace specific font color of all
style classes in one step?
For example, I have a few classes:
<style>
.header {
color: #F00;
}
.body {
color: #000;
}
.footer {
color: #F00;
}
</style>
Now I would like to replace 'color' value in all classes where it's
values is '#F00'. In real situation, there are 30 classes or more -
not just 3. If it is possible to replace colors using selectors it
would be great but I did't find any that would filter out elements
according to their CSS value.
Any help would be appreciated.
regards,
Miha
