I've uploaded a couple of illustrations and when the jpg preview shows there has been a color shift but only with certain images.  It seems brighter colors are uploading as a nauseating day glow color that makes me sea sick just to look at.  I'm working in RGB in illustrator and PS, and the files look fine in both.

I haven't been doing anything out of the normal in my work flow and upload methods but I have begun to use swatches from kuler.

I've had colors shift to a slightly duller tone before but not this, anyone know what's going on?  I'm guessing it has something to do with the swatches I'm using but one color of one swatch is affected in one jpg and not another.  

I'm on a PC running Vista BTW.

The site that you uploaded your images to may have converted them to CMYK. This would explain the color shift.

Hmmm...

So is it better to work in CMYK in Illustrator?

In my opinion YES....and watch your gamut  warning....
If you stay within the save gamut range your color will shift to almost non.

My work flow is make illustrations in AI with CMYK color mode.
Import that file to PS with RGB color mode and adjust in some cases the brightness or hue slightly .
(most of the time not necessary if I stayed within the save gamut range)

I'm still having this problem but I'm noticing it mostly with greens.

Uploaded pic at FT


I can't seem to upload a copy to any internet site that doesn't create the color shift, but the leaf in the bottom right corner should be a darker green to a cooler green gradient, but as you can see it comes out as just a bright green.  This file was created in CMYK with colors from the default color palette in AI.  Also the rest of the colors are somewhat accurate but have a brighter (not in a good way) tinge to them.

Any AI experts out there know what I am doing wrong?  Please!

Yeah, Thanks Kaycee, I did just like you said.  There was no gamut warning and when I select->color range-> out of gamut nothing shows up both when imported into PS in RGB and in CMYK.  Any other suggestions?

No I'm clueless.

I had the same problem and mine was out of gamut or very close to the out of gamut range specialy with the bright greens
