Wiki: This has been used way too much everywhere to be chalked up as an anime trope.

{{Seth}}: A lot of elves or witches in western mythology do this.

H. Torrance Griffin: Moved to RedEyesTakeWarning....
* In the recent ''{{Hellsing}}'' OAV, when Seras Victoria's eyes shift from blue to red (often glowing) expect bodies to hit the floor in numerous pieces. Not suprisingly, Alucard's eyes are always thus.

{{Qit el-Remel}}: The death knight voice modulation in WorldOfWarcraft is ''not'' a CreepyMonotone. That is, while it's certainly ''creepy'', it's not a monotone—just weird and hollow and sepulchral. (IMO, this calls for a [[YouKnowThatThingWhere YKKTW]].)

{{Meshakhad}}: I propose creating a separate category for the all-black eyes, as used by Dark Willow or the Phoenix.

{{Aereshaa}}: I propose making, also, a separate category for eyes that explicitly look like they are on fire.

linnen: What about {{KenichiTheMightiestDisciple}}? Or is that more of a Glowing High-beams of Doom trope?
