在ubuntu12.04下用eclipse或myeclipse做开发如果不更改主题的颜色的话，那就跟看着屎吃东西一样恶心。一坨又一坨的tooltip使你没有一点儿“胃口”去开发了。

废话少说，ubuntu12.04的所有主题在/usr/share/themes下面，我的主题是默认的（Ambiance）,打开nautilus，找到/usr/share/themes/Ambiance/gtk-2.0/gtkrc文件，这个文件就是该主题所有的颜色参数。我懒得一点点的看这个文件，因为在fedora下myeclipse的颜色还可以，所以就把fedora下的gtkrc文件粘过来了。下面是这个文件的内容，读者可以直接复制下面的代码(或替换gtk-color-scheme的值）到gtkrc，不过建议首先将原来的gtkrc做个备份（sudo cp ./gtkrc ./gtkrc.bak)

（其实也可以只改动gtk-color-scheme中的 ***_color属性值【其中的 **tooltip**_color就是一坨黑的罪魁祸首】）

另外通过改动base_color可以定制编辑区的颜色，例如:

gtk-color-scheme中base_color:#CCE8CF可以达到如下效果：

gtkrc文件内容如下：
