Indicating your working spaces in Photoshop

If you choose one of the predefined color settings, Photoshop plugs in all the necessary remaining options in the dialog box. (If you select the Custom option, Photoshop leaves whatever settings were there previously because it knows you are going to choose your own settings anyway.)

When you chose one of the predefined color settings, the first group of settings Photoshop plugged in were your working spaces. Working spaces are the color profiles associated with the RGB, CMYK, Grayscale, and Spot color modes. If you choose the Custom color setting, you need to choose your own working spaces.

Each of the four working spaces is equally important, so I advise you to read all the next posts — and read them in order — if you’re serious about color management.
