How to delete a color from the Apple Color Picker custom swacth?

The custom color swatch drawer is a great way to store custom colors that I repeatedly use in projects.

But how to delete colors from it? Click and delete does not work, click and drag it away doesn't work either... 

Only way I found is to click and drag the pot of color to the Trashcan! Simple enough... When you know it.

macOs Sierra Public Folder/Drop Box Resetting Original Permissions and Shared Public Folder Name Change

I deleted my Public folder from my User account, then I had to re-create it, with the Drop Box folder inside it. But it didn't behave properly.

1) First the permissions for the Drop Box were different from an original Public folder onto another computer. Namely the "Custom" permission was missing.

After a short Google search, I was able to bring back the Custom Permission using Terminal: https://discussions.apple.com/thread/6496223

DO AT YOUR OWN RISK

Open Terminal and type: cd ~/Public/

Make sure the Drop Box folder is present in there: ls

You should see: Drop Box

If you see nothing there, make a new Drop Box folder: mkdir "Drop Box"

Change the permissions: chmod 733 "Drop Box"

Change the permissions again: chmod +a "$USER allow list,add_file,search,delete,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,writesecurity,chown,file_inherit,directory_inherit" "Drop Box"

You now should see "You have custom access", Privilege "Custom" for the Drop Box Folder.  (Apple + I, or Right-click /Get Info.)

2) Second, the Public folder shows as "Public" on the network as opposed to "User's Public Folder" which is more convenient.

After a second longer Google search, I found these:

I am not going to reproduce what's already there, again DO AT YOUR OWN RISK. For me the process worked beautifully! Cheers!
