I'll add that pattern-matching of this kind for Association is in active development internally.

The tedious-looking workaround: {<|8 -> 7|>, <|"a" -> "red", 6 -> 3|>} /. a_Association /; KeyMemberQ[a, "a"] && a["a"] === "red" :> Nothing. The last example can also be done with KeyMap[]: KeyMap[# /. "a" -> "b" &, <|"a" -> 2|>].
