I noticed that Photoshop turns blue into purple. It's very strange... I look at a picture outside photoshop - filmstrip view in windows or anything else. When I open the image in photoshop, the blue areas turns purple.

Anyone noticed this before? I use sRGB color space both in my camera and photoshop. I attached a picture with an example. The left picture was opened in browser while the righ is the same picture but unedited in photoshop.

I should mention of course that the color it shows outside of photoshop is the correct color.

I'm rubbish with colour stuff, but is it not because windows doesn't use the Adobe colour space that it displays differently?

Which matches the view in camera?

photoshop is probably displaying the image using its actual color profile information, or it is converting the file to whatever color profile is set as its working default.

If your working color space is sRGB in Photoshop, then that does not seem to be the issue. The fact that other programs display the "correct" color is a clear indication that color management settings are still the root of the problem, however. Here are two possibilities:

- Look to see whether "Proof Colors" is checked; if so, PS may be displaying in another color space even though the working space is sRGB.
- PS may be using a monitor profile that is incorrect.

There may be other scenarios that could cause the observed behavior, but the two above are ones that come to mind immediately.

I have a similar problem... when I open an image in PSP and then open it in Photoshop, PS displays it as much brighter than PSP does. Or even ACDSee, Windows Picture viewer, etc.

Thanks for your help - I appreciate it!

I checked the "assign profile" area and noticed that it was set to not color manage documents. I flipped back and forth between this setting and the sRGB setting but it was almost the same. Then... I set it to the 5D profile setting (which I didn't even kow I had until now) and everything looks right!

But even on old 20D, 300D and my wife's current 350D images, it looks way off on the sRGB or "don't color manage" setting. The 5D setting cleans up all images regardless of which of these 4 cameras took the pictures.

It's still weird since it almost seems like images were being color managed in all other applications but I had to tell Photoshop to do it?!?

But in any case... I feel muuuuuch better!!! :)

Thanks a million Kirbic!

Agree with kirbic's assessment of most likely causes.

In Photoshop you need to check Edit>Color Settings.

Make sure working space RGB is set appropriate
(for you that's sRGB IEC61966-2.1)

Equally important are policies (or Photoshop may do something without your knowledge).

I set
RGB policy: Preserve Embedded Profiles
Check:
Profile Mismatches: "Ask when Opening"
Missing Profiles: "Ask When Opening"

This way you will know if the image color space is really embedded as you think and you will know what Photoshop is doing before it does it. This may help debug your problem.

One last item to check is whether you load a monitor profile intially at boot time (that may be used by Windows - and defaulted by other applications). If the monitor profile Windows is using is different than the one used by Photoshop - all bets are off.

Also, if using multiple monitors, Photoshop and Windows will have some difficulty using multiple color spaces. I use dual monitors: a good CRT for all photoshop work for print; and an LCD for the tool pallettes etc. and when converted to sRGB what the web users will see (at least the Windows users).

p.s. - you should be using Adobe RGB on your camera and photoshop - sRGB is a compressed version of the colors - Adobe is the full table of colors.

Tried the solutions (Photoshop should be working in Adobe RGB and should ask me before converting). When I open a NEF file in photoshop it looks fine, the exported jpeg looks fine in photoshop, the but the moment I open it up in any other program (Irfanview, Internet Explorer, Firefox, [Macromedia] fireworks) the color is different.

The image in that link shows the raw (NEF) image at the bottom, its produced jpeg at the top right, and the same jpeg opened up in Internet Explorer (same in all other programs). Note the color differences.

I'm lost, help if you can.

I've searched Google for this problem and ended up here. I figured out how to fix it for me (not sure if it'll work for everyone). But now my blue is blue instead of purple. Note, I am using Photoshop CS2.

First, click Edit -> Color Settings...
Under Working Spaces, drop down the box in RGB and choose "Monitor RGB - Your Monitor".

Second, click View -> Proof Setup
Choose "Monitor RGB"

Your pics should now look like they're supposed to. Hope this helps :)

What's the difference between sRGB IEC61966-2.1 and Adobe RGB 19something? My colors tend to look better when I use the latter but people say to use the former?

The Adobe RGB color space is larger than sRGB, that is, it can display a greater range of colors (wider gamut). Unless you really know color management, however, using Adobe RGB as your editing space is sure to lead to problems. If your primary output is web display, there's no reason at all to use Adobe RGB, since all web display is sRGB by default. If you're targeting print, and the output device can benefit from the wider gamut, then you might benefit. But first, read up on color management. It's a pretty complicated subject, so be prepared to spend significant effort.

I think most cameras which capture JPEGs do so into the sRGB space to start with. Is there any reason to convert that to AdobeRGB?

Many cams can be set to use the Adobe RGB space, and RAW data contains enough information to make that useful. For shots taken in JPEG using the sRGB space, converting to Adobe RGB *might* still be beneficial if editing would push come colors outside the sRGB space (but within Adobe RGB). Unless you know *precisely* what you're gaining by doing this, it is not worth it.

Pecisely what I thought. I don't think my 5 year old camera can change color spaces, but my own visual gamut is undoubtedly smaller (and different) than either of those, so I don't thnk I'll change anything : )

As always, in all his comments in this discussion, Kirbic hits the nail firmly on the head. The guy always seems to know what he is talking about. It is disgusting, isn't it? ;)

I would only add that I take all my pictures in sRGB in .jpg format. I've found that converting them to RGB and post processing in 16-bit ultimtely produces a much better final output even when later converted back to sRGB for a web graphic. If all you are ever concerned with is to produce 72 dpi screen output then it does not matter a lot what color space you work in. If you want to actually make decent prints of your pictures then always convert to Adobe RGB (1998).

That is what I teach students.

This has been a big help in that my images are blue as opposed to purple in Photoshop but I still have a couple of problems ...

1. They are still purple when I open them in Bridge
2. They are printing purple.
3. Now I have changed them to show as the monitor's RGB space and proofed them as the same have I reduced the scope of colours I can use?

Thanks in advance
