Hi Norm,
One of the interesting things about blend modes is how they are
grouped. Darken, multiply, color burn, linear burn are together.
Lighten, screen, color dodge, linear dodge are together, etc. Adobe
had their choice of how to group them and they chose these groupings.
Can you guess what delineates one group from the other?

Brgds,
Ron
