Compare 2 Tables For Exact Row (images Attached For Explanation)

I'm making a basic excel sheet as a hotel reservation tables. Sometimes we accommodate who do not follow the hotel regulation, so we add them to the black list table, made from (First name, Last name, Phone number). See image below:

Then if we reserve for a new customer, we use this sheet:

Here is my question:

what should i do, to make a raw color turn to red if i have entered a black listed visitor ?

e.g. if i enter "Martin" as a first name, AND "Issa" as Last name, AND "76344909" as a Phone. then the raw will turn to red to indicate that this customer is black listed.
