Google Sheets party formatting

Good morning
I was trying to color the line of holidays and Sundays of a Google sheet.
I encounter these problems
if those only on Sundays

1 = WEEKDAY ($ A4.2) = 7 it's ok, color the whole line from A: Z

2 = MATCH ($ A4, INDIRECT ("Holiday! D2: D"), 0)
those holidays ok.

If I combine the Sunday formula 1 with that of holidays: 2

= OR (WEEKDAY ($ A4,2) = 7, MATCH ($ A4, INDIRECT ("Holiday! D2: D"), 0))

I only color the lines of holidays 2 no longer Sundays 1
Is it possible to make a single formula or do you have to do 2 separate ones,
one for Sundays and the other for holidays?

what can i change i am just starting with Google sheets i am not very practical.
Thanks

Solved:

=OR(WEEKDAY($A4,2)=7,IFERROR(MATCH($A4,INDIRECT("Festività!D1:D"),0),0))
