> The particular concern this ticket addresses is to make it easier to identify
> which row is selected/highlighted after adding a new Controller Service to
> your configuration. This change would also make it easier to identify which
> row is selected when navigating a table with the keyboard, and fulfill the
> WCAG 2.1 success criteria "[Ensuring that additional visual cues are
> available when text color differences are used to convey
> information|https://www.w3.org/WAI/WCAG21/Techniques/general/G182]";.
> As you can see below, it is nearly or actually impossible for users with
> color contrast insensitivity (particularly a complete lack of color vision)
> to distinguish which row is currently highlighted.
>
> In the Controller Services table...
> Achromatopsia (grayscale):

> No color contrast vision problems:
