nuke navy blue

BUR #3215 has been approved by @evazion.

Of all the transition color tags, navy blue is the one we need the less, as it's just the default color for blue serafuku attire.

EDIT: The bulk update request #3215 (forum #170879) has been approved by @evazion.

A lot of these navy blue tags are being used for what I would call black. For that reason, I don't think blanket updating them to blue is a good idea.

I think somebody should at least go through all the lower tag count navy_blue items manually and adjust them to their closest colour.

I'm certain the navy_blue_legwear tag exists because navy blue socks (紺色ソックス) are a pretty specific and ubiquitous concept in Japanese culture, and I feel like the tag is worth preserving because of that instead of merging into another tag

-1 Out of all of the outlier colors to go after, the color that is perhaps the best defined and most easily identifiable was chosen instead of tan/beige/whatever. If I have to die on this hill though, then I want all other nonstandard colors to be removed, including those I already named, but also including lavender, aqua, silver, whatever other color which isn't one of the primary colors of Red/Yellow/Blue Orange/Purple/Green Brown Black/White/Grey... the end.

That's the aim, yes, but there's always pushback whenever someone tries to nuke one of these tags. Gotta start from somewhere, otherwise whenever we try to merge one of these tags the argument will always be "but what about X?".
If you want precedents, there's the maroon tags that were nuked a while ago.

The pixiv results are basically like every single post under blue_legwear serafuku. I wouldn't even be surprised if most blue_legwear -pantyhose posts currently on Danbooru are of that specific hue of blue.

+1 to this BUR. We shouldn't be tagging specific shades of already tagged colors.

Navy blue is a good choice precisely because it's so easily defined. It's simply a dark shade of blue, and as such is probably the easiest "outlier color tag" to mass update because it requires very little cleanup before it's ready to go. Some of the navy_blue_x tags should be black but most of them are fine to change to blue.

I can't help but notice think someone could see this as an impetus to want to keep the tags seperate, since it might be hard to find non-dark shades of blue if you merge the tags.

Then we should use something like dark blue legwear and light blue legwear, not something like "navy blue", which will always be mistagged because people use it because it's in the related tags rather than because it's what they see.

Note that it isn't even consistent what exactly "navy blue" really means, because like most pixiv tags it's something people add to get more visibility, not because it's accurate to the picture.

Some examples (all tagged as navy blue legwear at the time of this post):
post #3817256 (lightish blue)
post #3480062 (dark blue)
post #3441252 (looks almost grey to me)
post #3423885 (that's dark gray bordering black according to my color picker)
post #3269159 (blue-purple)
post #3056646 (just straight-out purple)

Having light and dark tags for each color would be a better solution, but it can be raised in another thread and would require months of tagging, as pretty much all posts on danbooru fit into either of the two categories for each color. It would be a massive retagging project and would require a lot of people to partecipate, and ultimately nuking tags that have a couple hundred posts would be irrelevant since we're talking about millions of posts.
There's also the issue that colors are subjective, so what someone might perceive as dark blue might be black or purple to someone else, depending even on things like the illumination in their room or the color calibration of the monitor. That's ultimately why having more than the "main" colors is a bad idea (see the nightmare that is silver hair vs white hair vs grey hair).

I agree with this one, because as stated navy blue is just one shade of blue. I do see the argument for making a dark blue or light blue tag instead as this "very dark blue" colour is common and looks very different to paler blues, particularly for specific items where one or the other is predominant. Similar to how we have a light brown hair tag.

I do not agree with doing similar things to the other, distinct colours that have been brought up in this thread.

While the tag is typically superfluous when it comes to legwear, sailor collars, neckwear, and skirts, it does stand out for usage in the color of a uniform blouse or the entirely of a uniform such as in navy blue serafuku. While that is true, I can't see any real difference between navy_blue_serafuku and blue_serafuku, and it looking through the former I'm already seeing some that are just black serafuku.

For reference, navy blue legwear was searched by 2 people over the last day and 9 people over the last three days. In comparison, black legwear was searched by ~250 people over the last day and ~750 people over the last three days. The rest of the navy blue tags get close to zero searches per day. So none of these tags are seriously used. And they're so undertagged and inconsistently tagged that you're going to have to comb through black legwear and blue legwear anyway if you really want to find all navy blue legwear.

Since we're settling on just having black and blue due to navy blue being underused, in my opinion, anything that is navy blue should be tagged as "blue". Objects tagged as "black" should be pure black and not a darker shade of an identifiable color. This goes particularly for school uniforms and legwear where there are a lot of navy blues but also a lot of outright black too (and sometimes on different characters in the same image as I gave examples of in forum #128953)
