The IMBLEND file that is relevant. Contains many different blending modes, and provides a base for adjustable blending mode feature idea in case any one wants to do that.
Due to DGM the IMBLEND author arrival in the open-source scene, he has provided a file which allows for more blending modes. So, what I did was translated them to Krita format, and added mod() to enable modulo operations, and created modulo operations. I will get the description of each blending modes pretty soon, but I will leave this differential for now. Now there isn't any missing blending modes besides ones from autodesk sketch (there is no formula for those, and workarounds is too costly, so I will not be doing those.)and of course LCH modes (this has to be enabled first, as of now LCH Color, and LCH Lightness are possible. Chroma or Hue isn't.).
One little detail I'd like to say before doing the more formal description of those modes:
Modulo operations allows for people to use Krita to generate abstract art, and glitch art. They also have the benefit of allowing manipulation of gradient to a fine degree. Just like binary modes, if you use gradients with those operations, you can generate a fine abstract art.
