Increase the visual difference between the Toolbar Icon Button on/off state

[myvuuu]

💡 Suggestion

Update toggle on and off state of the Toolbar Icon button to be more visually distinct.

Success Criteria

• The toggle on and off state of the Toolbar Icon Button are visually distinct (color contrast between on and off background must exceed 3:1 OR the component design can be altered to increase the distinction by inverting the color scheme, adding an outline, etc.)
• Toolbar Icon Button utilizes the new set of css variable tokens

Motivation

The toggle on and off state of the Toolbar Icon button isn't visually distinct enough for users with low vision / color blindness to defer the toggle state based on color alone.

Example

Please provide some examples of this suggestion in practice.
