Q5. What is an RGB profile?

A5. An RGB profile is a profile used to communicate what colors are viewed on the monitor to another device (in this case, this machine). Not only the individual monitors' profiles, but also the profiles of standard color space, such as sRGB and Adobe RGB, are included.

If you are using a general Windows application, it is recommended that you select sRGB.

If you are using an Adobe application, you need to consider the application's color management settings appropriately.
