My current usage is, need passing an object from UNIXServer to UnixSocket, i define a struct for serialize/deserialize from the JSON. string.

```auto
struct ProcessStatus
      include JSON::Serializable

      getter name, log_color # ...

      def initialize(
        @name : String,
        @log_color : Symbol,
         # ...
      )
      end
    end

```

But, JSON not support symbol, i get some things error message like:

```auto
 > 128 | begin
 > 129 |
 > 130 | ::Union(Symbol).new(pull)
                                               ^--
Error: undefined method 'new' for Symbol.class

```

And, Colorize not support string as argument

```auto
 3 | puts "hello".colorize("blue")
                           ^
Error: expected argument #1 to 'String#colorize' to be (Colorize::Color256 | Colorize::ColorANSI | Colorize::ColorRGB), Symbol or UInt8, not String

```

How to workaround on this?

Thanks.

Okay, i found the solution, there is an enum [Colorize::ColorANSI](https://github.com/zw963/crystal/blob/dacd97bcc/src/colorize.cr#L209) never mentioned in the doc
