Windows Image Color Management (ICM) 2.0 is the API that applications use to take advantage of color management capabilities in Windows. Windows supports using color profiles that comply with ICC.1:1998-09 File Format for Color Profiles to support flexible, state-of-the-art color control.
sRGB Color Space Profile. sRGB is the default color space in Windows, based on the IEC 61966-2-1 standard. An sRGB-compliant device does not have to provide a profile or other support for color management to work well.
