Color Picker shows RGB preview color in CMYK document

[DanH]

Start with a CMYK document—US sheetfeed uncoated, but maybe other profiles yield the same issue.
 

1. Place an RGB image—make sure it has some colors that are out of gamut for CMYK

2. Rasterize it

3. Use Color Picker tool (set to Point 1x1) to pick a color. Choose a color that originally would have been out of gamut.

4. If you have selected a color that was originally out of the CMYK’s gamut, notice the swatch next to the color picker's icon on the Color panel. It displays an out of gamut RGB color, while the Fill or Stroke swatch will display a CMYK color. See attached image.

If you use the color picker that is found in the Color panel, this does not happen. It chooses a CMYK color and displays it next to the color picker icon in the Color panel.

Edit: If this color is painted with, color picking the painted color yields the same out of gamut preview color—no matter which version of the color picker you use to originally pick the color, so even though the Color panel’s picker displays a CMYK color, it paints a color which the Color Picker Tool in the toolbar will display an out of gamut RGB preview of). End Edit

This behavior is identical to when you color pick from an RGB image that has not been rasterized. Initially I’d thought the reason for the RGB preview of the picked color was due to the photo not being rasterized, however, it still does the same thing even after the photo has been rasterized.

Same thing happens in Photo v2 on iPad.

Expectation: In the case of picking from a rasterized photo, I’d expect the “picked color swatch” to show a CMYK color.

Preference: In the case of picking from a non-rasterized RGB photo, I’d still prefer the “picked color swatch” to show a CMYK color, but perhaps there is reason for it to show the actual underlying RGB color as the color that was picked.

Hi @DanH,

Thanks for reporting this.

We do already have this logged with the Developers to resolve.

I'll update that report with a link back to this thread so we can update you when it's been resolved

Great! Came back to say, as you likely know, it isn't displaying the RGB color it used to be (before "conversion" to CMYK), but is displaying an even brighter color.

Also, why does the Color Picker tool pick from where the finger or pencil is touching, but the Color panel's picker picks from the center of the magnifier? Preference is the way the Tool works, some may not prefer it, so maybe an option to set it to how the user wants. Unless that is what this is, a way to give people their preferred way of the picker working. But it is confusing.
