Matrix background color by specific values in Rows and Columns

Painful but works

in Power Query
Click on Study --> Pivot Columns with %RT as Value

= Table.Pivot(#"Filtered Rows", List.Distinct(#"Filtered Rows"[Study]), "Study", "%RT", List.Sum)

Relplace All nulls with 0

click on Days ect.. and Unpivot other columns

= Table.UnpivotOtherColumns(#"Replaced Value2", {"Days"}, "Attribute", "Value")

Rename Attribute --> Study
Rename Value --> %RT

Change text color:
Text Color =
if( Max(Data1[%RT]) = 0 && Max(Data1[Study]) = "A" && MAX(Data1[Days]) <= 7, "#00FF00",
if( Max(Data1[%RT]) = 0 && Max(Data1[Study]) = "B" && MAX(Data1[Days]) <= 9, "#00FF00",
if( Max(Data1[%RT]) = 0 && Max(Data1[Study]) = "C" && MAX(Data1[Days]) <= 8, "#00FF00",
if( Max(Data1[%RT]) = 0 && Max(Data1[Study]) = "D" && MAX(Data1[Days]) <= 12, "#00FF00",
