Pick color from gradient stop

Jul 11, 2009 1:27 PM

 

Hi,

I am an absolute beginner with Illustrator and have spent the last few days experimenting. At some point I created a box with a gradient using a random color and would now like to figure out which color exactly I used on the end stop of the gradient.

 

I attached the sample to this post, you will notice that the smaller box on the black square has the gradient. If I select the darker stop (e.g. from the gradient panel) and then check in the color panel it says that it is black (RGB: 000), but as compared to the black square in the background it clearly isn't black.

 

I suppose I could just save the file as an image and then pick the color from with Photoshop, but it seems like there should be a way from within Illustrator?

 

Anyone can help explain how to do this or what is going on?

 

Thanks

Stefan

 

PS:

I am using CS4 on a Mac.

    Can't see the queued file...

     

    ...but its possible you've got an RGB 000 stop over a 100%k or a C40M0Y0K100 background. They will look different. Or opacity settings may be altering the appearance.

    Your attachment is unavailable. The Attachment feature of the forum is a waste of time and effort. Attachments remain "queued", meaning unavailable, for hours or days, leaving your question unanswered as it drops lower in the order of most recent post. Better to use the Camera icon to attach an image or to post the file online elsewhere and insert a link.

     

    But I would guess that your Document Color Mode (File menu) is CMYK. If so, use CMYK in the Color panel, not RGB.

    Attachement was realeased.

     

     

    Background uses R0 G0 B0.. Gradient uses 0K... that's why they don't match. Change the black stop of the gradient to R0G0B0 and they'll match.

    They aren't the same.

     

    Background is RGB, Gradient is Greyscale.

    I miss-typed.. it should have read 100K which means 100% Black.

     

    0R/0G/0B is not the same as 100K which is not the same a 100C/100M/100Y/100K.. they all have different appearances.

     

    To determine the color of the gradient, simply click a color stop in the Gradient Panel then look at the Color Panel.

    Actually the black square is a rich black Although I think illustrators color is somewhat off the charts and not fucntioning in a consistent and predictable manner. Because according to the color picker the 100% K is not really black which might be true as well.

     

    This is the color from the large square and now it matches but it is not 100% black so that is the problem.
    The rationale here is that the printed ink has a color to it which is not a pure black and the Printed image that appears as a real black is made up of more than black or K.

    Here it is as 100% K

    There's no such animal as an RGB Rich Black. "Rich Black" is a press term and only applies to CMYK artwork.

     

    Background is RGB.... Gradient is Greyscale.

    Thanks everyone for the answers, I think I roughly understand what's going on. Figuring out how this applies in the real world to something like a logo shared between the web and in printed form and getting consistent appearance already gives me headache without thinking too hard about it :-)

     

    Thanks again.

    If you think about it at all that headache will turn to pychotic episodes you will regret the rest of your life, so please do not think about it.

    Once again you are correct but also pointed out what happened. In order to reproduce what the OP did is that she has the color panel set to CMYK and is selecting the black on the lower right hand corner which as you wrote is 100% K and not RGB 000 as they thinks. If they stuck with the color swatches this and the same color swatch this does not happen as they are rgb swatches.

    '

    This is what they have done and don't realize it even though the document might be rgb. Although it is more likely that the document color space is CMYK and they made a swatch that is rgb 000.

     

    The OP should check the document color space in the file menu that will make it easier for them to work with consistent color.

     

    This is how they have the color panel set.
