Annotating in Preview

Sometimes I receive images of documents from friends in JPEG format which I then save on my Imac. Later I go an image to annotate it in Preview, select an arrow for example and choose Red colour only to find when I hit save that it saves it in a Grey colour.

If I was to print the image and scan it back to my imac I find I am able to save the annotations in the colour and way I prefer.

Does anyone know why I cannot save this doesn't work all the time, Please?

I am running into the same issue. I noticed that those .jpg files I am trying to annotate have "Color space: Gray" on the when I go into "Get info". The .jpg files that I can annotate without issues have "Color space: RGB" under "Get info".

Is there a way to make the "Color space: Gray" convert into "Color space RGB"?

Seems no one has this problem or an answer.

Only today I wanted to annotate a image (in JPEG Image format), I added text in colour (Red)

and hit save only to find it saved it in grey colour.

Is there no way I can adjust this problem

I have not been able to replicate the problem you're describing. I know that if you're saving a PDF file in Preview, there is the ability to apply a Quartz filter and one of the options is Gray Tone. Have you tried saving it as a PNG or another format to see if you can get the color to stay?

Hi Design Macster,

I think I have found the problem. I have been scanning some home made documents and some were done

in greyscale profile. When I then annotated them in colour text, it would save it in grey only.

By scanning the same document in Generic RGB Profile and annotating in colour text, it would be saved

with the coloured text showing.

If you think this could be the real answwer, please let me know.

That sounds about right. If you'd rather not rescan the document, you can try saving the files as PDFs in Preview, with Quartz filter set to none, and that may override the Gray Tone profile. If that works, you can then re-save the PDF as any image file that you'd like. It sounds like you were able to solve the problem on your own, good work.
