Faulty colors on save for web

Postby andersb71 on Thu Aug 02, 2007 1:43 pm

Hey guys, really hope you can help me:
when saving for web I get seriously wrong colors: http://www.flickr.com/photos/10859056@N02/986046580/

as you can see they are very different. what am I doing wrong?
It's a new MAC install of PS CS3 on a MAC Pro / apple monitor.

You should try some kind of color management program to check your screen colors, but I have no idea how those damn Macs work :P

thanks for answering but the monitor is calibrated and working properly, even if it wasn't the problem would still be there since you see already in the save for web dialog box

When you save for web, Photoshop automatically converts the image to web colors. Specifically, it uses the sRGB IEC61966-2.1 colorspace. Go to Edit> Color Settings. I'm guessing that under "working RGB", your space is set to either Adobe RGB 1998 or Apple RGB. Change it to the sRGB setting. Further down on the same menu, you'll see a check box marked "ask when opening". Check that box. Now, when you open your file (any file), if the colorspace of the file doesn't match your chosen colorspace (sRGB at this point), it will give you the option to convert the document to those colors.

Now you're comparing apples to apples (no pun intended). With the colorspace set to sRGB, you can edit the colors, and they won't change when you "save for web".

If you're not doing a lot of this, and don't want to change your preferences, it can be done to individual files. Go to Edit> Convert to Profile and choose sRGB IEC61966-2.1 from the drop-down menu. Photoshop then attaches the colorspace to that file only. It's still a good idea to check the "ask when opening" box however, so Photoshop doesn't automatically convert the file back to another profile the next time you open it.

Hope this helps.

Hey Medley, thanks for your great answer. It certainly helped, however only halfway. I have made a new dump with the save for web dialogbox open with correct colors compared, but in the top background you see the browser window from which I started my work, by taking a dump of that and the original is significantly darker in the blue than any of the versions in the save for web dialog box. what gives?

I just tried to setup my monitor in sRGB as well and that seems to solve the problem (almost anyway - still a slight difference)
Is that the way to go or is it "Wrong" to have your monitor set in that colorspace? also what if I get my monitor calibrated with that mousesensor you hang down in front of the monitor, then it'll create it's own profile, which then stops me from using a almost workable sRGB setting?

There is likely going to be a slight variation. sRGB is a smaller color space than most. So when you covert a document to those colors, there are going to be some colors that sRGB can't match. In this case, it will look for the closest possible color that it can reproduce. I think this is why you see a difference.

The beauty of converting the document to sRGB is that you can use Photoshop to tweak those colors to where you want them, and they won't change when you save. Since you're doing the edits in sRGB, you know that any edit you do is going to be directly usable by the web.

Open your screenshot (the "look" you're trying to match), then open the Photoshop file next to it. Use Photoshop to adjust the colors as closely as possible. It's not going to be perfect, because you don't have as many colors to work with. But, you can still get closer than Photoshop did when it converted it on the fly. YOU get to control how the conversion looks, rather than letting Photoshop control it. The end result is almost always a better looking file, and one that is still compatable with web colors.

When you set your monitor to sRGB colors, it controls how everything looks on the screen. I think you'll find that doing so changed how the original looked, rather than changing the file to match the colors of the original. The slight difference is probably due to the settings within the "save for web" dialog box. That's probably not what you want, but it still shouldn't change how the file you're working on will look.
