tooltip colored with legend

[daldoyle]

It would be really neat if the tooltip markup could somehow indicate a way to color the values according to the legend.

For example, the legend may use a light blue to indicate 50%. When I mouse over it and the tooltip appears I might want to show current, average, min, max and it would be visually nice if they could be rendered in the color corresponding in the legend. In this case it might be $input.now or similar
