gtk 用home-brew, brew install git 以后，如果报错误：

Error in startup script: unknown color name "lime"

 (processing "-fore" option)

 invoked from within

"$ctext tag conf m2 -fore [lindex $mergecolors 2]"

 (procedure "makewindow" line 347)

 invoked from within

"makewindow"

 (file "/usr/local/bin/gitk" line 12434)

解决方法一：

brew cask install tcl

解决方法二：

编辑gitk文件，把确实的color删除或修改。

解决方法三：

在home目录下配一个.gitk文件，将相关color定义一下。
