Change Google Drive Folder color with Apps Script

In Apps Script you can use the DriveApp service to manage your files and folders, but the methods getColor and setColor do not exist.

You can use the drive advanced service to query the API directly but with recent change you will have to activate the Drive API in GCP and will need a GCP project.

To have a smooth integration and skip the Google Cloud project creation here is a function to manage Folder color in Apps Script. These functions queries the API directly with UrlFetchApp() service.

REST API parameter

To manage color folder you have to use the parameter : folderColorRgb

Be careful, you can’t set custom Hexadecimal code. It must be one of the valid Hexadecimal code available in the About REST call (ref).

Get folder color name or hexadecimal code

// Get Hexadecimal code of the color used
folderColor.getHexa = function(id){
  var color = this.getColor(id);
  return color.folderColorRgb;
}
//Get Color name
folderColor.getName = function(id){
  var hexa = this.getHexa(id);
  Logger.log(hexa)
  for(var key in colorPalette){
    Logger.log(key + ' : ' + colorPalette[key])
    if(hexa == colorPalette[key]){
      return key
    }
  }
  throw "Error to get the color name please check Hexa value : "+ hexa;
}
// Helper to query API and get color parameter
folderColor.getColor = function(id){
  var url = 'https://www.googleapis.com/drive/v2/files/'+id+'?fields=folderColorRgb';
   var param = {
    method      : "get",
    headers     : {"Authorization": "Bearer " + ScriptApp.getOAuthToken()}
  };
  var html = UrlFetchApp.fetch(url,param).getContentText();
  return JSON.parse(html);
}

Set folder color name or hexadecimal code

// Set folder color by name
folderColor.setColorByName = function(id,name){
  if(!colorPalette[name]){
    throw "Name is not valid, please check name in colorPalette.";
  }
  this.setColor(id,colorPalette[name]);
  return true;
}
// Set folder color by Hexadecimal code
folderColor.setColorByHexa = function(id,hexa){
  for(var key in colorPalette){
    if(hexa == colorPalette[key]){
      break;
    }
    throw "Hexadecimal color code is not a valid code.";
  }
  this.setColor(id,hexa);
  return true;
}
// Helper to query API for setting color parameter
folderColor.setColor = function(id,hexa){
  var url = 'https://www.googleapis.com/drive/v2/files/'+id+'?fields=folderColorRgb';
  var param = {
    method      : "patch",
    contentType: 'application/json',
    headers     : {"Authorization": "Bearer " + ScriptApp.getOAuthToken()},
    payload: JSON.stringify({folderColorRgb:hexa})
  };
  var html = UrlFetchApp.fetch(url,param).getContentText();
  
  return html;
}
