How to change current week column header background color

Hello everyone i have this matrix visual that has already week number of year. i need to change current week column header backgorund color. So i am assuming it will be something like IF [myweekofyearcolumn] = [currentweekcolumn] then change current week column header color. (Text or background color)

This is how it looks like now. Columns are number of week. for example now we are in week 17 and i want the background color to be change for the current week
