The bulk update request #12452 is pending approval.
remove alias blue_iris (0) -> blue_eyes (595723)

remove alias green_iris (0) -> green_eyes (378071)
remove alias pink_iris (0) -> pink_eyes (70659)
remove alias red_iris (0) -> red_eyes (302118)
remove alias orange_iris (0) -> orange_eyes (72984)

remove alias purple_iris (0) -> purple_eyes (174335)
remove alias white_iris (0) -> white_eyes (40211)
Reason: Having [color]_iris as the main tag makes it much more obvious what the tag actually stands for.
For example the tag red_eyes might make someone falsely assume that means that any part of the eye can be red and not just the iris, resulting in that being often tagged on posts, that should actually be tagged red_sclera.
If BUR #12437 is approved, this would make this even more confusing, since in that case it actually means any part of the eye.
The followup BUR would look something like this:
alias amber_eyes -> amber_iris alias black_eyes -> black_iris alias blue_eyes -> blue_iris alias brown_eyes -> brown_iris alias green_eyes -> green_iris alias grey_eyes -> grey_iris alias orange_eyes -> orange_iris alias pink_eyes -> pink_iris alias purple_eyes -> purple_iris alias red_eyes -> red_iris alias tan_eyes -> tan_iris alias teal_eyes -> teal_iris alias white_eyes -> white_iris alias yellow_eyes -> yellow_iris alias multicolored_eyes -> multicolored_iris alias rainbow_eyes -> rainbow_iris alias two_tone_eyes -> two_tone_iris
Note that there are many existing aliases for these tags, so this BUR alone will not work.
