stderr from the target is not piped with correct color

[harunurhan]

Describe the bug
stderr from the target is not piped with correct color. For example we have a target that runs webpack devserver which outputs errors however it is not meant to exit. We use lage so we can run ^build a head of starting the devserver.

To Reproduce
Steps to reproduce the behavior:

1. Create a target that logs to stderr but exits with 0
2. Run that target with --verbose
3. Observe the output, stderr message will be greyed out.

Expected behavior
A clear and concise description of what you expected to happen.
