The name "Black" is automatically blocked when adding a new swatch

First posted this issue two-and-a-half years ago on https://illustrator.uservoice.com (https://illustrator.uservoice.com/forums/601447-illustrator-desktop-bugs/suggestions/44555385-the-na...)

When adding a new color swatch, regardless of the breakdown, the swatch name "Black" is automatically blocked if the 'Global' checkbox is checked. The swatch name "White" is not.

It seems silly to call this issue out, but I've prepared logo libraries for ten years now, and this has been an ongoing consideration. When I create a global black swatch, there is always an extra step. Sometimes I misspell the name to create the swatch, or I create a non-global swatch with the correct name, but in both scenarios I have to adjust the swatch AFTER it is created to produce a global swatch with the name "Black." The same extra step is not required for a white global swatch with the name "White."

A comparison of my workflow below—

Black Global Swatch:
1. Remove all swatches from the file
2. In the Color palette, click the 'Black' color shortcut
3. In the Swatches palette, either click the 'New Swatch' shortcut at the bottom or select "New Swatch..." from the menu
4. In the New Swatch dialog box, change the default name (depending on color mode, either "R=0 G=0 B=0" or "C=0 M=0 Y=0 K=100") to "Black"
5. Check the 'Global' checkbox
6. Select "OK"
7. No swatch appears in the Swatches palette

White Global Swatch:
1. Remove all swatches from the file
2. In the Color palette, click the 'White' color shortcut
3. In the Swatches palette, either click the 'New Swatch' shortcut at the bottom or select "New Swatch..." from the menu
4. In the New Swatch dialog box, change the default name (depending on color mode, either "R=255 G=255 B=255" or "C=0 M=0 Y=0 K=0") to "White"
5. Check the 'Global' checkbox
6. Select "OK"
7. A swatch appears in the Swatches palette

It's a reserved name, just don't use it:

As the name can be used through counter-intuitive workflows, any user motivated on grounds of inclusion will recognize a systems resistance that has no constructive purpose — an enforced difficulty and challenge associated only to the usage of the name "Black." This may be a legitimate confirmation bias issue and worth the investment required to remediate.

Cyan, Magenta, Yellow and Black are printing inks and their names are reserved. 

It is that simple.

"Black" and "White" logo files are industry standards (notably, as prepared solutions for design situations where colors/inks are limited), and global swatches are generally preferred by production designers for their utility. It can be disconcerting to repeatedly face programming, within the circumstances I've described, which produces the outcomes I've described.

[Ton Frederiks]

If you double click the Black swatch in the Swatches panel, you can make it global.

If you want all your new print files to have that global Black swatch, you have to edit the Print new document profile.

But you can rename the swatches if you want.

So, if you rename Black to fgdtyh, you can create a new swatch named Black, you just cannot create a swatch name that does already exist.
