  We construct a Kirby color in the setting of Khovanov homology: an ind-object
of the annular Bar-Natan category that is equipped with a natural handle slide
isomorphism. Using functoriality and cabling properties of Khovanov homology,
we define a Kirby-colored Khovanov homology that is invariant under the handle
slide Kirby move, up to isomorphism. Via the Manolescu--Neithalath 2-handle
formula, Kirby-colored Khovanov homology agrees with the $\mathfrak{gl}_{2}$
skein lasagna module, hence is an invariant of $4$-dimensional
$2$-handlebodies.
