RGB Color Mode
Professional monitors are pricey but they can be tuned or matched to very precise output settings.
CMYK Color Mode Counter Intuitive
CMYK contains 1 more channel than RGB but it has a smaller color gamut.
Its color gamut is designed to meet the narrower color range needs of the four-color printing process.
Except for the Bitmap-mode image, all images in Photoshop can have up to 24 channels. These are frequently called alpha channels. Sometimes, the alpha channel can be used to decrease file size.
I added the Actions to my Palette set by a simple drag and drop process. Grab the Actions tab and drag it off to remove it from the Palette.
