	"fmt"
	
	"github.com/mithrandie/go-text/color"
)

const (
	BlueColor   = "blue"
	YellowColor = "yellow"
)

type Config struct {
	Palette              color.PaletteConfig `json:"palette"`
}

var jsonConfig = `
{
  "palette": {
    "effectors": {
      "color1": {
        "effects": [
          "Bold"
        ],
        "foreground": "Blue",
        "background": null
      },
      "color2": {
        "effects": [],
        "foreground": "Magenta",
        "background": null
      }
    }

`
