You had the input sheet named List and I named the output sheet Output. And here's the code.

function condCopy()

{

  var s = SpreadsheetApp.getActiveSpreadsheet();

  var sht = s.getSheetByName('List')

  var drng = sht.getDataRange();

  var rng = sht.getRange(2,1, drng.getLastRow()-1,drng.getLastColumn());

  var rngA = rng.getValues();//Array of input values

  var rngB = [];//Array where values that past the condition will go

  var b = 0;//Output iterator

  for(var i = 0; i < rngA.length; i++)

  {

    if(rngA[i][1] == 'blue')

    {

      rngB[b]=[];//Initial new array

      rngB[b].push(rngA[i][0],rngA[i][2]);

      b++;

    }

  }

  var shtout = s.getSheetByName('Output');

  var outrng = shtout.getRange(2,1,rngB.length,2);//Make the output range the same size as the output array

  outrng.setValues(rngB);

}
