How to change background color in matrix table based on values

[Anonymous]

Hello everyone, 

Haven't done anything similar before, I am currious if I am able to change background color based on value in matrix table. 
I have country column as you can see from image and two countries are columns values (spain and portugal) and some values about counties. 
I would like to have red color if the values are not matching and green if the values are matching. 
I have tried few things but the meausre I was creating wasn't good.

@Anonymous , You need to create a measure like , assume you have measure M1

color =

var _diff = if( calculate([M1] , Table[country] ="spain") = calculate([M1] , Table[country] ="Portugal") ,1,0)

return

if(_diff =1, "Green", "Red")

Use this in conditional formatting using filed value option
