Why won't my colors convert? (PS)

OK, here is my issue. I have a map that I have done in Photoshop, and I like the colors that I have, but when I save it as a JPG, the colors are different. What am I doing wrong?

Here is a sample of what I am talking about. The first pic is the JPG output, and the green is jarring and ugly. The second is a screen shot with the accurate colors.

Try saving it as png, and see if the color loss is there as well.

Are you using "Save As" or are you using save to web? Not sure of all versions of photoshop, but one of the options in the save dialog for "save as" is a checkbox for colour profiles. Mine defaults to having it unchecked, and i've never had an issue with colour changes. perhaps that's what's happening? I also noticed one in the save for web dialog. it's called ICC profile in both places.. mine are unchecked.

But... they are both jpegs?

How do you normally overcome this then? Because I've never seen one of your maps with greens like the first image has (although I happen to quite like that colouring :) )

I can't help with this problem, but the second version looks very good!

And a map that contains one of the Dutch provinces (Friesland) is always cool :D

I use the "Save As" command, and I have done it with ICC checked and with it not checked.

I have done some maps that has this problem before, and I have always gone back into the PS file and changed the colors until I got something that worked well enough.

I will try to save it again as a GIF using the "Save For Web" and see what happens.

Weird. My first thought was that looks right like an ICC issue... The map wasn't created with an ICC profile. I don't think some of the JPG format saves ICC info - it might have been expanded tho. I thought maybe the save with to JPG which does not have it and save without one is the same thing. Try saving as TIFF and see by opening in the MS Picture Viewer to see if its alright.

Am I right in that you said the second image is a screenshot and the first one is the actual saved file? I'd say it's a monitor issue...looks like your monitor is a little bit lighter and grayer than what PS is using.

Or if it's like mine, the jpegs I save always seem to be different colours when viewed through Windows Picture Viewer. I'd have a mess around with the "Color Settings..." but it seems ok when viewed through Firefox as an attachment.

Make sure that you've calibrated your monitor for use with Photoshop. It has this annoying habit of tweaking the gamma as part of its startup, which means that your final image will not be the same as what you're working on.
