ribbon chart - indicate current day

It seems like conditional control in only available when you have only one series

color = if(max('Calendar'[Date])=date(2020,02,15),"red","green")

I was able to change color using the Field option and a measure. The same way it has been given here https://docs.microsoft.com/en-us/power-bi/desktop-conditional-table-formatting#color-by-color-values

You need to try like

color = if(max('Calendar'[Date])=Today(),"red","green")

Hi, hugus 

Based on your description, I created data to reprodue your scenario.

Table:

You may create two measures as below.

DisplayColor = 
IF(
    SELECTEDVALUE('Table'[Date]) = TODAY(),
    "red","blue"
)

visual control = 
var _date = SELECTEDVALUE('Table'[Date])
var _datediffago = DATEDIFF(_date,TODAY(),DAY)
var _datedifffuture = DATEDIFF(TODAY(),_date,DAY)
return
IF(
    OR(
        AND(
            _datediffago>=0,
            _datediffago<=5
        ),
        AND(
            _datedifffuture>=0,
            _datedifffuture<=7
        )
    ),
    1,
    0
)

Then you may make the visual selected, go to 'Visualizations' ribbon, click 'Format'=> 'Data colors'=>'Conditional formatting'. You may set it as below.

Finally you need to put the 'visual control' meausre in the visual level filter. Here is the result. It displays the data in the past five days and the data in the next seven days.

Best Regards
