sRGB
When it comes to picking a color profile, Pic-Time suggests uploading photos with an sRGB profile. sRGB is the currently recommended color profile for screen viewing and commercial printing. Using this profile as the delivery profile is safest when it comes to your clients getting the same colors you intended on screen and in print.
Adobe RGB
That being said, Pic-Time supports photos with the Adobe RGB profile and will preserve and use the profile correctly through the gallery display and production process. It is important to note that many monitors on the market today don’t support larger color gamuts than sRGB, therefore some color variation might occur when viewing.
