Photoshop out of gamut for printing

[Lewis5E7D]

Im trying to change the colour of a photo on photoshop but everytime i go to select a colour it goes back to grey and says that its out of gamut for printing. I dont know what this means so any help would be great

[NB, colourmanagement]

I presume you have Photoshop's "view/soft-proof" set to your actual printer's ICC profile and "gamut warning" is switched on.

Ideally you are working on a calibrated and profiled display screen?

What Photoshop reveals by imposing the (default grey) gamut warning overlay, is that your image has areas of colour which are going to be remapped significantly during conversion to the printer profile - because they are beyond the printer gamut*.

When they remap undesirable changes of appearance may occur.

[*meaning that ink and paper simply cannot match the image colour.]

In many cases, simply printing (using Photoshop Manages Color and the printer / paper profile) will actually give an acceptable result. But, if, when you print, you see unacceptable colour shifts or flattening of detail or perhaps lightening, specifically in the area that Photoshop had highlighted - then you'll need to edit the offending colour area before printing.

Often a little desaturation can help, sometimes using selective color so that only certain colours are affected by your edits.

This process takes practice.

But don't be over alarmed by the gamut warning, if you have the printer and can make a test print that’s a good way to learn what it actually means in practice.

Let the eye decide.

I hope this helps

Hi @Lewis5E7D ,

Check that you are not working in Grayscale mode.

Image Menu > Mode.

Choose CMYK if you plan to print your work.

RGB if you plan to use it on the Web or in Video projects

That statement seems nonsensical. 

Which Color Space are you working in?

What is the target Printing Space? 

Please post meaningful screenshots.
