+Colorable writer for windows.
+
+For example, most of logger packages doesn't show colors on windows. (I know we can do it with ansicon. But I don't want.)
+This package is possible to handle escape sequence for ansi color on windows.

+## Too Bad!

+
+
+## So Good!
+
+![](https://raw.githubusercontent.com/mattn/go-colorable/gh-pages/good.png)
+
+## Usage
+
+```go
+logrus.SetFormatter(&logrus.TextFormatter{ForceColors: true})
+logrus.SetOutput(colorable.NewColorableStdout())
+
+logrus.Info("succeeded")
+logrus.Warn("not correct")
+logrus.Error("something error")
+logrus.Fatal("panic")
+```
+
+You can compile above code on non-windows OSs.
