BROWSING THE INTERNET ON A WIDE GAMUT MONITOR
If you have a general purpose monitor that works in the sRGB
colour space on a limited number of colours this won't apply to
you. This section is for when a wide gamut aRGB monitor is used only.
It is fortunate that as 95% of internet users use an uncalibrated
general sRGB monitor and don't understand colour management, that
the sRGB standard was designed so that most monitors under most
conditions will produce reasonable colour.
Although things are slowly changing, web browsers (largely) ignore colour management and assume that
anything posted on the internet is sRGB. It is only when you come
along with your fancy aRGB monitor that things start to go
wrong as we shall see.
If you view a web image (sRGB) on an aRGB monitor using an non-colour-managed
browser then the image will appear oversaturated on your screen.
All web browsers except Firefox are non colour-managed at the
time of writing, but they are improving and hopefully will all
hopefully sort themselves out eventually. However, at the moment I strongly
advise you to start using Firefox as your browser if you wish to avoid the
Even Firefox hasn't got everything right unfortunately. There
are some occasions when the image tag that effectively says "this
is an sRGB image" has not been embeded into the image when it wsaa posted (could that be you ?) or has
been stripped out or lost at some stage. For some strange reason
Firefox then makes the unfortunate assumption that the image should
be assigned a tag that effectively says "treat this as an
image with the same colour space as your monitor" in our
case aRGB. So we hit the same issue as in problem 1 of oversturated
An unmanaged browser such as Internet Explorer does not even read
these tags. It just assumes everything is sRGB, so this issue
doesn't arise under these circumstances but more by luck than
judgement. So why not use an un colour managed browser ? If you work in sRGB that would be fine, but not for us aRGB masochists. If you posted an aRGB image onto the internet, IE would think it is sRGB and it would look very washed out and unsaturated.
RULE 1. When posting images on the internet, only post sRGB images or 95% of your audience will see them as washed out.
The browser solution
To get the best of all worlds in problem 1 and 2 on the current
version of Firefox at least, it is necessary to modify Firefox
to treat untagged internet images as being sRGB not monitor RGB
There are two ways of doing this. One is described in this article:
but there is a much easier way and that is to add a purpose designed
Firefox extension designed by a helpful chap called Sean Hayes.
Now come out from behind the sofa - it is not difficult to add
a Firefox extension I promise. Here is a step by step guide:
After you have downloaded the latest version of Firefox, open
it and then click on Tools>Addons>Extensions and search
for colour management in the search box. When you have the Colour
management addon by Sean Hayes (version 0.5.3 or whatever the
current version is) click on Options and select "All images"
and also enter the path to your monitor's profile. The easiest
way of finding this is usually to look in the software that you
used to calibrate your monitor as described at the end of Part
If you have not calibrated your monitor then there is little point
reading any more until you have as it is the most important thing
that you can do in this whole colour management thing.
In the case of the Eizo, when using the Eizo Color Navigator software, the path to profile appears on page 1 of the software in
"Detail" called path to Profile. On my computer it put
Chances are if you use a PC that it will be somewhere similar,
if using a Mac you will need to search around a bit to find it. Using teh search function to find files ending in .icc shoulkd also come up trumps.
Once you have the path you can cut and paste it into the relevant
Firefox Extension box.
Restart Firefox and you are done !
Where are we now ?
You will now have calibrated your monitor, will be using Firefox
with an extension added and will be seeing beautiful and accurate
colours on your monitor when you surf the internet despite having
an aRGB monitor.
In the next section we will deal with working in Photoshop with
your wide gamut monitor and considering how to save images to
the web in such a manner that anyone else viewing them stands
the best possible chance of seeing them correctly.
