Full Idea
Why not view 'red' as naming a single concrete object extended in space and time? ..To say a drop is red is to say that the one object, the drop, is a spatio-temporal part of the other, red, as a waterfall is part of a river.
Gist of Idea
'Red' is a single concrete object in space-time; 'red' and 'drop' are parts of a red drop
