Still a small factor, I think. People have different
OSs, different monitors, different monitor settings...
If a page depends on the browser recognizing color
profiles then the webmaster doesn't know what
they're doing. Webpages are simply not designed
for that kind of precision. Nor are computers, for
that matter. It's one thing to calibrate your own
computer to your printer. It's another to expect
that you can pass on that accuracy to someone
else's machine.

Interestingly, when I first went to that page I
saw the yellow car. I then tried changing the Firefox
pref for gfx.color_management.mode, trying to
figure out what prefs might affect the display, but
nothing changed. Actually, I tried the setting to
always apply color management. Today I see the
purple car in both Firefox and Pale Moon. Yet it
was only in PM that I made any settings change
in the first place, and I later changed that back
to the setting to only apply color management for
tagged images.

I also see a purple car when I download the image
and view it with various software. The author didn't
explain how the purple vs yellow shows. When I look
at the image bytes I see a simple JFIF, no EXIF data.
