Hi Gregory,

What it means is the following: usually, selections are "in or out": a pixel is
either selected or it is not. Krita uses a more sophisticated way, in which
pixels can be fully selected, fully unselected, or partially selected. In total,
there are 256 levels of selection. I don't know the technical details, but
probably 0 is unselected and 255 is fully selected.

Partially selected pixels are only partially affected by operations, e.g.
color changing - the operation will only take (for example) 1/2 of the pixel
color values. So if a white pixel is coloured red, but is only half selected, it
will become a color midway between white and red.

Hope that this is clear enough.

Cheers,
