I always work with ProphotoRGB, which is good for saving clipped areas...and then convert it to sRGB and upload it to DT.

@Afagundes, as far as I know retina display use an IPS panel and I think the software settings are much more important then the quality of the monitor. I have both a Mac, an iPhone and a high tech PC...I don't see any serious difference between them.

well, the problem is not so simple... The display itself can be able to display the adobeRGB colors correctly, BUT there are more things in the play - first the DT page - as far as I know - is not capable to attach AdobeRGB into previews of our photos, second the web browser - almost non of the browsers has ICC profiles supported and when they support it, than it usually it is not turned on by default... The last step is the device display and device color management - the device can have excellent display, but with disabled device color management it will spoil the colors...

So what happens with AdobeRGB files - first the DT page rips off the profile thus sends distorted colors to web browser, than the browser has no information about color space so it uses sRGB as default = incorrect color representation... Even if DT would embed AdobeRGB profile in the preview image, then in 90% cases the browser would ignore the profile and display the image as it is sRGB image = incorrect colors.

So the safest way is to upload sRGB image to have preview shown in correct colors. The conversion to sRGB should be the last step in post-production to achieve the less distorted colors. (This way you "cripple" the image when it is finished, not at the beginning and than try to revive the killed colors...)

A pair of eyes, one regular-sized brain, and some stuff for ...

I use Adobe RGB, although sometimes I'll try ProPhoto RGB (even broader colorspace). All photoshop writers I have read recommend Adobe RGB or ProPhoto RGB. However when an image is currently used on the web, an Adobe or ProPhoto RGB color space may look flat, and so it is recommended to convert the profile to sRGB as the destination color space. The Convert to Profile, for those who haven't used it before in Photoshop, is under the Edit tab. This allows for the best of two worlds. The image has been processed in Adobe or ProPhoto RGB and so has a broader color gamut, which may be important for future use, but it is converted to sRGB for current web use, without losing the value of the Adobe/ProPhoto RGB.
I have no technical insight regarding retina displays, but I will say that the colors of my Adobe RGB images are gorgeous on my iPad:)
Currently my primary camera is a Fuji XT-1.

Thats why I asked Adeliepenguin, but I think Janceluh´s answer give it all we wanted to here, stick to sRGB even if its the last step before uploading.

AFAIK Adobe RGB is indeed wider - meaning if you stick to 8 bits of color per channel, with Adobe RGB you will loose some color "resolution" (the steps between adjacent hues will become larger, creating more problems when shooting very smooth gradients - like golden hour sky hues). sRGB has more narrow gammut, and as a result - higher color resolution for a given bit depth.

Ideally, one would have to save the final result in a widest gammut possible (like Adobe RGB, or even wider) and 16 bit color, to keep both the extent of the colors and the color resolution. In practice, I think it makes more sense just to keep the original RAW file, and then save the output to the exact target - if it goes to web, as sRGB, if it directly goes to printer, Adobe RGB.

It's a no brainer sRGB is for web display and RGB is the clour space that is normally used to transfer images that will end up on or in printed material. For printed material printers can use either RGB or CMYK, one usually finds that a printer running a dgital press will acept files in RGB format whereas a traditional printer will most probably require CMYK.
This is keeping it simple, the next thing is ICC profiles that is another blog.

Also if you have a highend inhouse printer like EPSON, you will use RGB and have an ICC profile that will match your printer and paper/card stock you are printing.
