Pro tip: Calibrating your monitor every two weeks and uploading sRGB images to Pass ensures that your images will print correctly at our partner labs.
sRGB
When it comes to picking a color profile, Pass 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
Adobe RGB is a larger color space than sRGB and is often used for professional printing. Adobe RGB is too large of a color space for the web, but it can be converted to sRGB for online publishing.
