Blending Modes
Blending modes are named after the ones used in Krita.
Depending on the application, a blending mode with the same name may have different results. When a blending mode is set in OCA, its result should be the same as the blending mode with the same name in Krita. This choice was made because Krita is a free and open source software, so anyone can have a look at how these blending modes are implemented, to be sure about what they do, and because Krita uses one of the biggest list of blending modes.
The implementation of these blending modes is described in details in the Krita Reference Manual.
To know the correspondance of the blending mode names and implementations between Krita/OCA and the most common other applications, we’re building correspondance tables (see below).
Krita Blending Modes
This table lists the correspondance between OCA Blending Modes and Krita Blending Modes.
As OCA Blending modes are based on those of Krita, all of these are exact matches and should be considered the reference implementation of them. See Krita.org and the Krita Reference Manual for more information about them.
If a blending mode is not listed in this table, that means it is not supported by OCA (yet).

Adobe After Effects Blending Modes
This table lists the correspondance between OCA Blending Modes and Adobe After Effects Blending Modes.
If a blending mode is not listed in this table, that means it is not supported by After Effects and there is no approximation close enough.
