Hello - I have some images in indexed mode and my Photoshop CS 4 won't let me edit them - how can I get them out of indexed mode?

here's a screenshot of my work area:

      Beg to differ but you can select either CMYK or RGB (or Grayscale or Lab for that matter). User's choice.


      Sorry, I was a bit gruff and obtuse. I meant to imply that converting to CMYK is a bad idea and just going to RGB is better. I stand by that, since the colours in the file are already RGB, and I rarely have a need for CMYK Photoshop files.

      Simple fix! Just go to the Image menu, choose "Mode", then select RGB or CMYK.

        Correct, except for “or CMYK”

        True, but since the original poster did not specify what they were going to do with the edited file, either color space is viable. And it's unlikely that the average user editing png will be troubled by the color shifts should they occur. Colors have to be well beyond the gamut edge to be troublesome and SRGB to CMYK is not that tremendous of a jump. In addition, they'll probably have a more intuitive understanding of editing color in CMYK (closer to the pigment mode of crayola crayons that we've most of us been accustomed to since pre-school) than in RGB.


        You're making a lot of assumptions about the OP and apparently have not converted enough images from RGB to CMYK to not have noticed a difference. CMYK offers an extremely limited range of color.

        In grade school, we are taught red, yellow and blue as primary colors with paint and crayons - - - not cyan, magenta and yellow.
