Change the color of the wrap around arrow

Question

So I would like to change the color of the arrow that shows the text is being wrapped. Specifically the red arrow shown here:

I have tried searching myself and the closest I came is finding out the sides are called "fringe"s and this answer. But where I hit a stump is figuring out the syntax of the function, set-fringe-bitmap-face bitmap &optional face.

I assume means something like this: (set-fringe-bitmap-face 'left-curly-arrow ((t (:foreground "#616161")))) But my problem is I don't know how to write the correct syntax for a [face] symbol. Also I don't even know if this would do what I want which is just to change the color of that red arrow to something that fits my theme.

Thanks for any help.

Answer 1

I do not know about the color #616161 as my Emacs version doesn't seem to display a big enough difference in the color for me to see it with my naked eye, but here is an example using "yellow".

(defface my-custom-curly-face
  '((t (:foreground "yellow")))
  "Face for fringe curly bitmaps."
  :group 'basic-faces)

(set-fringe-bitmap-face 'left-curly-arrow 'my-custom-curly-face)
