Amphidromus multicolor is a species of air-breathing tree snail, an arboreal gastropod mollusk in the family Camaenidae.
(Original description in Latin) The shell appears smaller and yellowish. It is painted with reddish-brown, brown, and greenish streaks, often displaying a flammulated pattern.
(Description as Amphidromus multicolor gracilior) The shell is white and features oblique, semi-transparent, pale horn-colored stripes. The apical whorls are generally filleted.
(Description as Amphidromus nigrofilosus) The shell is nearly covered, perforate, and ovate-pyramidal, exhibiting a sinistral coiling and obsolete striations. Its color is white and shining, obliquely painted with pale corneous lamellae. The spire appears elongate, with a very minutely crenulate suture. Comprising seven subconvex whorls, the last four are sutured with an intense black line, and the last whorl is compressed at the base. The aperture is broadly subquadrangular and somewhat twisted at the columella. The peristome is straight, white, callous, and expanded throughout; the columellar margin is strongly calloused and recurved, displaying a violaceous hue.
This species is endemic to the Philippines.
