If you prefer a more noticeable color (as I do) for the matching bracket highlight in Eclipse, you may be a bit mystified when Aptana’s matching bracket highlight does not use the system-wide setting, nor does Aptana appear to have a setting of its own for setting the color.  Here’s a quick tip for customizing the matching bracket highlight color for Aptana’s editors.

1. Go to Preferences > Aptana Studio > Themes
2. Change the Caret color

It turns out that Aptana uses their own caret color setting for the matching bracket highlights.  It’s not very intuitive, but at least it’s still possible to customize, as long as you’re okay with a differently-colored caret.
