>  1. text on color bar, this is the background-color, and the text is unreadable at line 1 (black on black)
>  2. the same color as foreground-color, the black text is readable on my normal background color
>  3. the RGB hex values

> I am saying the problem is in column one where WYSIWYG background-color and text color are identical it is unreadable.

Could be foe some combinations, but then the color name is legible in
the other column.

> I’m suggest in column one, where the black text is too close to the background-color being demonstrated, such as blue, medium blue, that the text-color in column one should be inversed to white from black.

Volunteers are welcome to submit patches to do that.
