Set different highlight-line color for emacs --no-window

Question

How can I set a different color if I am using emacs on terminal (emacs --no-window)?

I use a grey highlight line when using emacs with GUI because my background theme is white. Here is the code I use in my ~/.emacs.

(global-hl-line-mode +1)                                                                                                                      
(set-face-attribute 'hl-line nil :inherit nil :background "#e6ffff")

However, when I am using emacs on terminal it has a default black background and this highlight colour looks awful.

You detect your window sytem with window-system. See this question.

In terminal mode this variable is nil, so you can change the face in this case.

(when (not window-system)
    (set-face-attribute 'hl-line nil :inherit nil :background "#888888"))
