Modify a font colour that has no colour name

Modify a font colour that has no colour name

[jonetsu]

Doing C-u C-x = on a org mode link shows the face that's used.
Although the colour of the face turns out not to be a colour but a
name, 'link'.  If a colour is put in this field, the links disappear so
to say, and no colour is applied.  Is there a way to change the colour
of that face and is it possible to do it only for the links in org mode
(although I do not mind if all links everywhere are adopting the same
colour) ?

Thanks.

Links in org-mode use the 'org-link' face, so you can just do 'M-x
customize-face org-link' and set the attributes you like.

Without digging into the code, is there a way to find this out (in the
general case)?

Do M-x customize-face, but don't press return; the prompt will
tell you which face you're about to customize, and then you can
press C-g.

HTH,

No code needed: C-u C-x = will tell you which face is being used by
the character under point.

On the first screen, yes.  Where it shows:


  There are text properties here:
  face                 org-link

'org-link' is a link itself.  Clicking it gives another screen, with
two links at the top:


Face: org-link (sample) (customize this face)

Clicking 'customize this face' gives another screen which shows the
well-known field where to enter the colour name.  On that screen
'Inherit' is enabled and in lieu of the colour the following is shown:

Face: (sample) link

'link' is where the colour name would be.  Changing 'link' for an
actual colour name it does not give good results.  Hence my question.

'Inherit' means 'inherit everything from this named face'. If you want
to set the colour directly, you should click on 'Show All Attributes',
and then set the 'Foreground' attribute as desired.

Thanks, this works very well.

I also disabled 'Inherit' while changing the foreground colour and added
an underline.

There's a function that lists all the faces and their colors, but the
name I forget.  The ones that are difficult to see you then 'customize'.

M-x list-faces-display RET, maybe?

M-x list-faces-display
    ;; Let people alias that name to list-all-faces?
    ;; I really can't remember list-faces-display.

If you are creative (ha) enough, you just need
to remember the name of the faces:

Do it today, in a different way!

; does not compute

Probably in newer Emacs, right?

Because "font" is a more modern word?
