Hello, Ive missed one point: when printing, another setting in the dialog Color Settings mentioned below may be of interest: in my German speaking GIMP its "Farbanpassung der Drucksimulation", which is about Color Adaption for Printing Simulation: here you can choose Saturation-Perception-Absolute Colormetric-Relative Colormetric. The default Perception ist what I would suggest at first, but you may try something else. If you do so, it may be important to mark ~Printing Simulation in ~Working Mode (Im not shure about the expressions, first dropdown menu in the window Color Management). Another point mentioned earlier is: if the monitor had not been calibrated correctly, the color deviations may habe been written to the image. Using menu Colors>Hue/Saturation: Hue might help, when preselectig the color range you want to correct.
Regards

Standard color profile for photos and images is none or sRGB. Photoshop imports images from scanners and cameras, which usually produce images based on that standard sRGB. As far as I can remember, even if you create an 24 Bit image in PS, sRGB is used when saving. Another standard is the Adobe proprietary Adobe RGB, which is a "broader", more colorful variety of the standard RGB (sRGB) color profile, mostly used for printing. You can download the Adobe RGB color profile for free from Adobes website (just do a search for Adobe RGB in a searchengine), save it to disc and implement it in GIMP: menu Edit>Preferences>Color Management. If an image is in Adobe RGB, opening the image in GIMP results in a warning message, asking whether you want to keep Adobe RGB or convert it to sRGB. You may try setting Adobe RGB as default in the menu mentioned, or just open your image in Adobe RGB and print.

This is a complex problem wrapped in a short-ish email...

Is your monitor calibrated and profiled? Did you also generate a profile for your printer? If not it's not going to be possible to accurately gauge or anticipate what your prints will look like compared to what you see on your monitor. :( On Wed, Sep 21, 2016 at 8:34 PM James Moe wrote:

Color profile: sRGB Printer Driver description: EPSON PictureMate PM 225 with driver Epson PictureMate PM 225, Epson Inkjet Printer Driver (ESC/P-R) for Linux

I have a Epson PM225 inkjet color printer.

I have printed images previously with the printer and there was no noticeable difference in color. The printer has been not used for several months. There has likely been some GIMP updates during that time.

Currently, when I print an image that has a blue sky, the printed color has a strong green tint to it, not really close to the displayed blue sky at all. Other images have printed similarly with the green tint.

I have tried changing ink cartridges. No difference.

The online manual mentions that the display uses RGB while printing is CMYK. It does not discuss what to do there is a mismatch between the two.

Any suggestions about what may be done to correct the color issue?

The monitor is not calibrated.
How do I create a profile for a printer?

Well that may be.
It does not explain the printer's distinct color shift when it was previously mostly correct.
Previously: blue printed as blue.
Currently: blue prints as green-ish.

The GIMP and Photoshop use different color models: RBG in the GIMP and LAB (if I recall correctly) in Photoshop. Color conversions between the two will be, at best, approximate.

What's a color standard? Do you mean ICC profiles? What's proprietary

material here?
