Also Blood Music by Greg Bear.

It’s a short story and also a novel.

Same thing, but biological rather than nanotech.

Green goo!

ETA: Oh there’s a grey goo color code: Grey goo: The basic stuff. Turns everything else into grey goo.
Green goo: The bio version. Basically all life forms are levels of green goo. (By observing mice in a grain silo this becomes readily evident even at the macro scale)
Red goo: The military version. Presumably can be directed by commanders. Presumably.
Blue goo: The cleanup version, specifically attacks grey goo and turns it into blue goo.
