Theme unable to redefine default colors, e.g. black and white

[Andrew-Starr]

Description

If we want to remove the default colors, we can do so with settings.color.defaultPalette : false in the theme.json

But, if we want to still have access to the black or white colors for example by including these in the theme's color palette, they are not available as of #36811

I don't quite understand the reasoning behind blocking themes from defining colors with the same slug as a default color, if the theme is removing the default palette. Black and white are elementary basic colors that a theme may want to use, whilst at the same time not using the other default core colors.

Now if we want to include a black or white color, we have to give it a different slug, but we shouldn't have to do this as it will lead to confusion.

Step-by-step reproduction instructions

Remove the default core color palette, and add a black color to the theme color palette, for example:

"settings": {
		"color": {
			"defaultPalette": false,
			"palette": [
				{ "slug": "black", "name": "Black", "color": "#000000" }

Edit a post or global styles and notice the black color is not available for selection, even though the theme is defining it.

Never mind, I found this will be addressed in #37008

So easy to miss issues/PRs when searching! Will close this as not needed.
