Check if any cell in specified range meets 2 conditions

I'm putting together a macro that sends alert e-mails if two conditions are met.

The e-mails are being sent, but indiscriminately and not just when the conditions I want to set are being met. The conditions: send an e-mail if any cell inside the range (I1:I9999) has white as background colour AND contains the text "QC". This is what I have tried:

 var QCJobRange = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("WIP").getRange("I1:I9999"); 
  var Location = QCJobRange.getValue();

  // Check for white cells with value=QC in Location column

  if (Location = "QC") and (Background = "#ffffff");

// Fetch the email address
var emailRange = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("WIP").getRange("C2");
var emailAddress = emailRange.getValues();

// Send Alert Email.
var message = 'bla';
var subject = 'bla';
MailApp.sendEmail(emailAddress, subject, message);

I'm working directly in the script editor that you can open from Google sheets. It seems that some operators are not being picked up, f. e. "and" is not even highlighted and I get the following error message: "and" is not defined.

I've been combing the forums for a simple solution but am kind of stuck on the problem with "and". Any suggestions?
