Issue with PS CC, blue isnt blue

I agree with D Fosse about the possibility of a defective monitor display profile

Display profile issues 

At least once a week on this forum we read about this, or very similar issues of appearance differing between applications.

Unfortunately, with Microsoft hardware: Windows updates, Graphics Card updates and Display manufacturers have a frustratingly growing reputation for installing useless (corrupted) monitor display profiles.

I CAN happen with Macs but with far less likelyhood, it seems.

The issue can affect different applications in different ways, some not at all, some very badly.

The poor monitor display profile issue is hidden by some applications, specifically those that do not use colour management, such as Microsoft Windows "Photos".

Photoshop is correct, it’s the industry standard for viewing images, in my experience it's revealing an issue with the Monitor Display profile rather that causing it. Whatever you do, don't ignore it. As the issue isn’t caused by Photoshop, don’t change your Photoshop ‘color settings’ to try fix it. 

If you want to rule out pretty much the only issue we ever see with Photoshop, you can reset preferences, I never read of a preferences issue causing this problem though:

To reset the preferences in Photoshop:

Note: Make sure that you back up all your custom presets, brushes & actions before restoring Photoshop's preferences. Migrate presets, actions, and settings

To find out if this is the issue, I recommend you to try setting the monitor profile for your own monitor display under “Device” in your Windows ‘color management’ control panel to sRGB. You can ADD sRGB if its not already listed. 

And be sure to check “Use my settings for this device”.

(OR, if you have a wide gamut monitor display (check the spec online) it’s better to try Adobe RGB instead).

Quit and relaunch Photoshop after the control panel change, to ensure the new settings are applied.

If this change fixes the issue, it is recommended that you should now calibrate and profile the monitor properly using a calibration sensor like i1display pro, which will create and install it's own custom monitor profile. The software should install it’s profile correctly so there should be no need to manual set the control panel once you are doing this right. 

Depending on the characteristics of your monitor display and your requirements, using sRGB or Adobe RGB here may be good enough - but custom calibration is a superior approach.

I hope this helps

if so, please "like" my reply and if you're OK now, please mark it as "correct", so that others who have similar issues can see the solution

thanks

The predominant green in the Colour picker cube is because you have the "R" Red button checked - change it to the "H" of HSB to see the blue Hues

As for the actual Hue, make sure that your monitor profile describes your monitor, as described by Dag above, and that you are working in a similar colour space (if non is specified in Paint Tool and comes into Photoshop without a profile, then assume sRGB and assign that in Photoshop) . The same RGB numbers describe different colours in different workspaces so it is important that any colour described by RGB numbers is in the context of a colour space.

OK, that looks very much like a corrupt/defective monitor profile, probably distributed from the display manufacturer through Windows Update. That happens a lot and is a very common problem. Why they can't get it reasonably right is a mystery. Worst offenders are Samsung, LG, Acer, Asus and Dell.

Applications without color management don't use the profile and are unaffected.

What type of display do you have? If it's a standard gamut display (99%), replace your current profile with sRGB IEC61966-2.1. If it's a wide gamut display, use Adobe RGB or P3 depending.

Relaunch Photoshop when done, it loads the profile at application startup.

Most likely Paint Tool Sai (whatever that is) does not support color management.

Don't ever "mess" with Photoshop color settings! Don't change anything if you don't know what you're doing. The defaults are safe settings.

Beyond that, we need a screenshot to see what you mean. Insert it in the thread, don't attach. Attachments don't seem to work at the time, and most of us are also generally hesitant to click unknown links.

Please set the Status Bar to »Document Profile« and post meaningful screenshots on this Forum directly.
