How to change color style of TextField in flutter

Question

I have a simple TextField widget like this

TextField(
      obscureText: widget.placeholder == "Password" ? _isHidePassword : false,
      decoration: InputDecoration(
        
        hintText: "${widget.placeholder}",
        hintStyle: TextStyle(
          color: Colors.grey,
        ),
        // labelText: "${widget.placeholder}",
        // labelStyle: TextStyle(color: greenMain),
      ),
    )

and it gives the result like this picture:

is there a way to change the blue color into another? like red or green one ?
