Photoshop color picker is Monochrome

[Firstnamelastname]

Upon Launching my Favorite Adobe application, Photoshop, I found that the Color picker took will only select monochromatic color options, no matter which color I intended to select. I have attempted to fix the issue using CTRL+2, and by restarting, in my opinion, Adobe's greatest application, Photoshop.

Hi. If that happens with any image try resetting the preferences: https://helpx.adobe.com/photoshop/using/preferences.html#reset_preferences

If a Layer mask was targered they are a gray scale channel only shade of gray will be sampled. Its more a limonsity sample than a color sample.
