Why does my computer display jpegs in inverted colors?

It happens when I save psd files as jpegs.

[Nancy OShea]

On Windows, hold down Windows key + +(plus) to open Windows Magnifier. 

Hold Ctrl + Alt + i to invert colors.  Repeat for normal colors.

[rivkat18478041]

Thank you for your reply. I tried that and it helped me view the correct colors, but this is only a temporary solution to see the good colors. Is there a way to solve this issue permanently, I should be able to see normal color when opening jpegs?

You didn't really answer the request from John T Smith​ :

I wasn't sure as there may also be 3rd party programs. What version do you use?

[rivkat18478041]

Currently, I use v 20.0.2 but this was created in v 19.1.7.

Make sure the file is an8-bit  RGB jpeg.

Please clarify exactly where you are seeing the jpeg inverted. In photoshop, or in some other app like placing in an email program?

Are you sure the colors are showing incorrrectly, or did someone possibly do a CTRL I for invert image? Black Is 0 RGB  in your info palette, white is 255 RGB.

[rivkat18478041]

I see it in file explorer and when I open it with photos.

[Mike_Gondek]

Does it look correct in Photoshop, if not do a CTRL I and save.

[rivkat18478041]

In photoshop it does look good.

[rivkat18478041]

It's a cymk jpeg.

[Lumigraphics · Accepted solution]

A lot of software can't handle a CMYK JPEG file, they expect RGB. Try converting to RGB.

[rivkat18478041]

Thank you! It works perfectly! So, should I always convert files I create in photoshop to RGB before saving?

[D Fosse]

CMYK is for commercial offset presses only. Anything else - RGB.

[rivkat18478041]

Please explain. What do you mean by commercial offset presses?

[D Fosse]

An offset press is what prints books and magazines, as opposed to a home/office inkjet printer.

In any case, as Lumigraphics said, very few photo viewers have proper CMYK support.

[Mike_Gondek]

CMYK is for print (Printing with inks)

RGB is for digital display purposes (Displaying with light)

[Abambo]

You should avoid changing from one colour model to a different one, if there is no need. CMYK has his merits, but it should be converted at the latest moment possible. Data acquisition is all RGB or even much more low level (raw). Keep files as long as possible in their original file format.

[D Fosse]

Well, in any case - we don't know the OP's intentions with this file, he hasn't said. So we don't know whether RGB or CMYK is appropriate.

What is clear is that a standard photo viewer most likely doesn't support CMYK at all. So that's the immediate answer to the original question.

Please help us understand your workflow:

• Why are the jpegs coming to you in CMYK?

• Were they originally in RGB and then converted to CMYK?

• What is the final output?

[rivkat18478041]

It was CYMK and the output is CYMK. Should I output my CYMK jpegs in RGB?

[D Fosse]

That's impossible to answer unless you tell us what the files are intended for.

What we have told you is that CMYK files won't display correctly in most photo viewers, because it's not supported.
