The tag alias #73083 color_request -> invalid_tag has been approved.

Reason: Some dude is adding this to images he wants to see colored. This is annoying when it's only comments, but outright obnoxious as a tag. Ranges from sketches to linework to non-greyscale monochrome to spot color.
Requesting an alias because at least one other person has used this tag and in case anyone else gets the same idea in the future.

EDIT: The tag alias color_request -> invalid_tag (forum #422227) has been approved by @spe.

Weird that it's also been added on some fully colored posts.
Regardless, there's effectively no difference between this and searching monochrome for finding things to be colored.
