Can you elaborate on the request? Like what you actually want, a feature to customise each character of a captcha.

if so, I can let user to enter the specified character, for example:

  1. please enter the red characters
  2. please enter the biggest 2 characters many many possibilities

by the way, is it a bug in captcha.ts: 

if (option.colors && option.colors?.length > 2) {this._ctx.fillStyle = option.colors[getRandom(option.colors.length - 1)];}

should it be: 

if (option.colors && option.colors?.length >= 2)

Yupp it is a bug. Actually I never use option.colors so I never noticed it. Thank you for raising it 😅
