With my last two submissions to DA I realized that the colours that show in my PS are totally different from the ones online. And I mean "totally different".
Yep, in general, images you're posting to the Internet should have no color profile, or sRGB. One quick fix is to go to Edit > Assign Profile, skip any warning you might receive, and select "Don't Color Manage This Document". Also, in Edit > Color Settings, pick "Monitor Color", which should turn off color management. Most browsers don't use color profiles, so they'll appear different than what Photoshop shows you if a profile is set.
You might want to consider profiling your monitor, or at least setting an appropriate "color temperature" for the lighting situation in your room.
Anyone knows how can I solve the problem?
