colorize (only with console transport) doest not work with custom format

[Minyar2004]

Please tell us about your environment:

• winston version?
  • winston@2
  • [ x] winston@3
• node -v outputs: v10
• Operating System? (Windows, macOS, or Linux) windows 7
• Language? (all | TypeScript X.X | ES6/7 | ES5 | Dart) javascript

What is the problem?

Problem with colorize()
`

const winston = require('winston');

const customLogFormat = winston.format.printf(info => {
  return `${info.timestamp} [${info.module}] ${info.level}: ${info.message} `;
});

const logger = module.exports = winston.createLogger({
  level: 'silly',
  format: winston.format.combine(
    winston.format.timestamp({
      format: 'YYYY-MM-DD HH:mm:ss'
    }),
    winston.format.errors({ stack: true }),
    winston.format.splat(),
    customLogFormat
  ),
  defaultMeta: { module: 'nomModule1' },
  transports: [
    new winston.transports.File({
      filename: 'fileLog.log'
    }),
    new winston.transports.Console({
      format: winston.format.colorize()
    })
  ]
});



logger.debug({
  message: 'myMessage',
  a: 'a',
  b: 'b'
});

`

What do you expect to happen instead?

Expected behavior: levels should be colored in console transport, but with the code above colorize() does not work and level are not colored...

It does work.
You are giving the format property on global level.
Give it inside the transport property like shown here
