    Let's get to the point... You can't!

    Color Space View in Color Picker Tool is either RGB or Lab based (which in a way does make sense since I suppose you don't have a CMYK screen, do you? ^^ But on the other hand, I understand that a CMYK color space could be handy, although not 100% accurate, even with a calibrated screen *)

    Now, if you want to pick up CMYK colors, I suggest you forget about Color Picker Tool and work only with swatches.

    Next question will probably be: how do you know the CMYK value of the color you want to create without seeing it on screen?

    My answer would be: use a CMYK printed color guide... That would be the most accurate way...

    Hope that helps

    Hi Vinny,

    Barb did a link to a thread where Rob is explaining that Color Picker indeed is able to convert RGB to CMYK using InDesign's Color Managment. I toyed a bit with the panel in InDesign CS6. It's not that intuitive, but you can convert a picked RGB value to CMYK values and also see the managed preview on screen.

    Step 1:

    Pick a color like: 0, 255, 0 in RGB

    A color that cannot be printed with CMYK. The underlying color management tries its best and is suggesting 66, 0, 100, 0 for CMYK.

    Step 2:

    Set your cursor to any of the CMYK value fields.

    Note this, the preview color of the green next to the OK button still does not change.

    Step 3

    Edit one value, e.g. type in 1 into the K field. Confirm the edit with typing Tab on the keyboard.

    Now the preview changes to the color managed color in CMYK:

    Regards,
    Uwe

    Hi Uwe.

    Cool! I didn't know that trick.

    That's how this dialog box was designed. There isn't an option to display the CMYK color space. This thread may be helpful: RGB Color Space to CMYK Color Space view

    Vague.

    Do you mean the eyedropper tool?

    If so, then taking a colour sample from an RGB image or graphic will give you RGB values, to change them to CMYK use this:

    Then you can add the colour to your swatches in CMYK.
