    I was playing around adding some HTML entities to Günter’s Special Characters Plugin for convenience, when I noticed this.
    The down-arrow character (& #8595) has a coloured vertical bar instead of being black like the rest. Sometimes it’s purple and sometimes it’s green? The point of the downarrow is always black (body font color), like it should be.

    I know, this is completely unimportant and irrelevant, but still, it bothers me not knowing why it happens. :-)

    This only happens on the downarrow character happens on downarrow, uparrow and vertical bar and only with Enfold, whether entered manually or with the plugin, it shows black (body font color) in other themes.

    Anyone have an idea as to why this happens?

    Cheers,
    Rob

    PS
    Seems to be only happening with FireFox (latest), OK in Chrome
    Happens in FireFox & Chrome too, but only at normal zoom level. Zoom in enough and it becomes black again…. Happens at every zoom level. When used in Headings some are black, some are colored, The normal vertical bar behaves the same. Line length (number of characters before the downarrow or vertical bar seems to decide the color it shows. The plot thickens…and my bewilderment too :-)

    Hey Rob,
    Sorry for the late reply and thanks for the login, I found your test page, but your arrows are black for me, zoom in or not, please see the screenshot in Private Content area.
    The color is determined by the classes of the parent elements, so it is possible for the characters to be different colors depending on where they are placed.

    Best regards,
    Mike

    Hi Mike,

    Thanks for looking into this, it’s a really strange phenomenon.
    Especially since I also see the colors on the screenprint image you posted :-)
    line 1,3,5 on the image show green vertical bar
    line 2 and 4 on the image show purple vertical bar
    I was suspecting it could be my screen only but it happens also on another screen.
    And the arrowpoints are always proper black.
    I notice it more when I have the luminosity turned up, but it is really there for me. And the strange thing is it disappears when I do the same on a different theme.
    Remark:
    The “classes of the parent element” doesn’t explain why all lines under normal <p> have different colors depending on the number of characters before the vertcial bar/downarrow/uparrow

    I am stumped. :-))

    Kind regards,
    Rob

    Hi,
    Sorry, I don’t see different colors, but it does look like an optical illusion if I stare at it. But the inspector is saying that all are black.
    I notice this looks different if you change the font, try this css to see what I mean:

    #top.postid-8903 .entry-content p {
	font: initial !important;
}

    Best regards,
    Mike

    Hi Mike,

    Thanks for that. I added the CSS, and indeed it is different then, just more noticable :-) See for yourself.
    I added a next blog post with two screenprints (png24 because more accurate), one before the CSS and one after.
    To my eyes there is a definite color change for anything that has a pipe character.
    In the original blogpost with the issue I added some lines with normal letters like L undercase and I undercase and b to show the difference in color better.

    In short: the best way to see it is to do 3 lines in a paragraph:
    xxxxxxxxxxetc.
    \\\\\\\\\\\\\\\\\etc.
    ||||||||||||||||||etc. (pipe)
    /////////////////etc.
    wwwwwwwetc.
    I hope I don’t need an eye doctor, or a new laptop :-)

    Hi Mike,

    I just realised how completely nonsensical this comparison discussion is. A traditional LCD screen has continuous backlight, so it never gets completely black due to light leakage. Real (O)LED displays use a LED per pixel and per color, so the black is (at least in theory) completely black.
    So unless some Enfold user out there works in the graphic design industry and has a combination of professional grade graphics card & monitor (like Nvidia Quadro or AMD Radeon Pro, with a EIZO ColorEdge 27″ or Dell Ultrasharp 32″) and professional calibration, there will always be differences,

    My beef was more about the color difference between characters on the same screen. As as black on LCD screens doesn’t exist, at least theoretically red, green and blue etc. should not suffer the same fate. And of course the “pipe” character is more susceptible, since it is so thin.

    But let’s just leave this behind us, I’m sure we all have bigger fish to fry than the color artefacts on a pipe character :-)
    Sorry for taking up your time wih this!

    Regards,
    Rob
