Data Color Is not Visible | conditional format fx not visible for custom colors

Create a mesure for color logic:

Order Date Color =
VAR _MaxDate = MAX('YourTable'[ORDER_DATE])
VAR _MinDate = MIN('YourTable'[ORDER_DATE])

RETURN
SWITCH(
SELECTEDVALUE('YourTable'[ORDER_DATE]),
_MaxDate, "#FF5733", -- 🔶 Orange for the latest date
_MinDate, "#3498DB", -- 🔷 Blue for the older date
"#808080" -- Default Gray (just in case)
)

Then apply condiotional formatting based on this measure.

Hi Raghu3636，

Actually, there is no direct way to apply conditional format for a dynamic date on the Legend in Power BI, which is by design.

If you want this feature to be supported, you could raise an idea here:

As a workaround, you could consider to configure your bar chart as below, then create a measure to apply this condition format:

Date Color = 
VAR MaxDate = CALCULATE(MAX('Table'[ORDER_DATE]), ALL('Table'))
VAR MinDate = CALCULATE(MIN('Table'[ORDER_DATE]), ALL('Table'))
VAR CurrentDate = VALUES('Table'[ORDER_DATE])

RETURN
    SWITCH(
        TRUE(),
        CurrentDate = MaxDate, "Max", 
        CurrentDate = MinDate, "Min", 
        "Other"
    )
