I don´t know if it´s possible...

why don´t you mix your CMYK colors in Window>Color palette? Color ramp is a bit small but if you just input CMYK values, it´s quite handy...

EDIT: I did a small test with color picker and discovered that if you click your cursor to any CMYK value field, "Add RGB swatch" turns to "Add CMYK swatch"

Yeah, i am doing it.

But using the color picker view has become a habit as i used it in all other other adobe softwares.

This is just a doubt. Why in a software which is mostly used for print production rather than web purpose, RGB Color space view is put and not cmyk color space. This question is asked to me by many of my friends & colleagues and i have no answer

did you try to put your cursor to any cmyk-field in color picker? it should change RGB to CMYK...

The "Add RGB Swatch" Turns into "Add CMYK Swatch". but i want the color picker to show as "CMYK Color Space View". I think it is not possible to change to "CMYK color space view". I need to pick a cmyk color. Now we are seeing the RGB color space and picking rgb colors then changing into cmyk. is there any way to pick CMYK color other than using "Color" palette.

I don´t think you can do that with color picker.

I pick colors with eyedropper to Color panel, and use Add to Swatches command in Color panels menu to transfer it to Swatches list.

The Color Picker lets you easily get a color managed conversion of a color from one space to another. So, 0|0|0|50 CMYK might be equal to 148|148|148 RGB, but there are also many possible conversions of 148|148|148 RGB to CMYK depending on the press profile—it could also be something like 44|36|36|2.

The Color and Swatches panels let you make CMYK builds, but the don't let you easily make conversions between spaces.

The ID color picker is strictly a RGB tool (other than being able to create a CMYK or Lab "equivalent" swatch, which inthe case of CMYK porbably won't be very close most of the time due to gamut restrictions), and is a very dangerous place for you to go when working in CMYK. Besides not showing the muting of out-of-gamut choices, should you have someting selected with a cmyk swatch or spot color applied, open the color picker and say OK to exit without creating a new CMYK swatch (something you might do instead of hitting Cancel), your selected object will be converted to RGB.

You really should try to get used to using the Color Panel, or even the Swatches Panel, until a real CMYK color picker is added. I use the CMYK ramp to get close, then use the sliders to fine-tune CMYK colors.

As long as you leave your cursor in one of the CMYK fields when you click OK or Add CMYK Swatch, the Color Picker lets you spec any CMYK build. While you don't get visual gamut clipping in the color picker field (if you are picking from the field), the swatch or color is brought into gamut when you click OK.

The Color Picker does let you convert built CMYK colors via color management, which isn't easily accomplished elsewhere. If you want the CMY equivalent of 10% K based on your CM settings, you can get it by building 10% K as 0|0|0|10 then clicking on the cursor in the color field. Or you could easily get a legal version of a color that exceeds a total ink limit, something like 100|100|60|60 in the same way.

Rob, I'm not sure I follow your thought process here.

Doesn't working in the color panel, starting with RGB sliders and ramp, then switching to CMYK sliders and ramp convert the RGB to the proper CMYK build for the current working space in exactly the same way as the color picker making the CMYK swatch, except that it doesn't round the precents?

My point about the danger is that your cursor is NOT going to be in a CMYK field unless you put it there intentionally. Properly used, I'm sure Color Picker can be very valuable, but I don't hink it can do anything that can't be accomplished in other ways, and I've seen too many files with destroyed spots and what people thought were matching CMYK mixes where one object was converted accidentally to RGB to think the Color Picker is a worthwhile tool.

Your right using the eyedropper in the Color panel you can pickup color managed CMYK values. Getting a color managed version of a built CMYK color, something like 20|0|0|20 (which you would never get in an RGB>CMYK conversion, or find in the color field), is more problematic in the Color or Swatch panel. You would think you could dial in 20|0|0|20, switch to RGB, then back to CMYK and get the conversion, but that doesn't work—the original CMYK values are remembered.

Is there no way to click on any area of a page, and have the color readout transfer into the color picker? Or the color panel? Or the swatches panel?

The eyedropper being object based does not seem to do this properly.

You should be able to load a color into the Color panel (but not the Color Picker or Swatches) via the Eyedropper. When the eye dropper icon is pointing right it's loaded and will apply it's attributes to an object when you click it. When it's pointing left it's empty and gets loaded when you click an object. To empty the dropper click the pasteboard or no object.

To pick up color in the Color panel hold down your Option key and the eyedropper will pick color without applying anything.

And it's really easy to move a color from the color panel to swatches. Just drag it or right-click and select add to swatches.

When you go to "File" "New" to open a new document, be sure to select "print" instead of "web" from the drop down menu. Then your color palette will show CMYK color space swatches. If you select "web" when opening a new document, you get the RGB palette. It's Adobe acting like Microsoft and trying to outsmart you by making decisions for you.
