Weird color behaviour about telephone-line HOT 6 CLOSED

That is odd, but sounds familiar... Are you on OSX? I seem to recall something about Emacs on OSX having screwed up colors in images (the color discrepancy in your image is between stuff that is rendered as text and stuff that is rendered as images)

EDIT: Err.. OSX, MacOS, whatever they call it these days :/

That seems to be the problem I'm dealing with. Adding (setq ns-use-srgb-colorspace nil) to my config seems to fix the issue. Unfortunately, that just disables srgb colors everywhere, which makes everything look rather ugly.

Thanks for the pointer! I'll see if I can find a better workaround and post it here if I find something.

I looked into it a bit, there's a patched version of emacs over here: https://github.com/railwaycat/homebrew-emacsmacport

I can also patch it within telephone-line, but considering how there's something like this unpatched in upstream, shouldn't there be other things fixed in that? I don't know if it's right to fix one bug to help people use the more buggy version, if you know what I mean.

Powerline (and some other plugins) seem to have built-in workarounds, but I agree with your approach.

Thanks for looking into this!

I closed this since this seems to be an upstream problem. If I do find some workaround (which does not rely on the mac port), I'll post it here.

(setq ns-use-srgb-colorspace nil) works for me as a workaround.

In powerline, colors are converted from sRGB color space to Apple RGB on macOS.

(defun pl/color-srgb-to-apple-rgb (red green blue)
  "Convert RED GREEN BLUE colors from sRGB color space to Apple RGB.
RED, GREEN and BLUE should be between 0.0 and 1.0, inclusive."
  (apply 'pl/color-xyz-to-apple-rgb (color-srgb-to-xyz red green blue)))

(defun pl/hex-color (color)
  "Get the hexadecimal value of COLOR."
  (when color
    (let ((srgb-color (color-name-to-rgb color)))
      (if powerline-image-apple-rgb
          (apply 'color-rgb-to-hex (apply 'pl/color-srgb-to-apple-rgb srgb-color))
        (apply 'color-rgb-to-hex srgb-color)))))
