在初始文件的最后添加：
;; 选中标签设置为绿底黑字，其他标签为黄底黑字
(set-face-attribute 'elscreen-tab-other-screen-face nil:background "yellow" :foreground "black")
(set-face-attribute 'elscreen-tab-current-screen-face nil:background "green" :foreground "black")
备注下elscreen原始代码：
(defface elscreen-tab-current-screen-face'((((class color))(:background "white" :foreground "black"))(t (:underline t)))"Face for current screen tab.":group 'elscreen)(defface elscreen-tab-other-screen-face'((((type x w32 mac ns) (class color)):background "Gray85" :foreground "Gray50")(((class color))(:background "blue" :foreground "black" :underline t)))"Face for tabs other than current screen one.":group 'elscreen)
emacs defface
