In the EUI documentation, the EuiBeacon component is defined to be used as "...to draw visual attention to a specific location or element."

The current component displays with a slowly blinking icon in the green color.

This component would likely be more useful if it had a color property that could default to 'green' for backwards compatibility but also allow the user of the component to set a different color (e.g., 'warning', etc) in different UI contexts.
