Chalk uses
supports-color
to determine what color level should berendered. However, currently our parent
ava
process uses that tocolorize its output, however, when we fork our test processes we clobber
the color configuration that
supports-color
uses to determine thelevel (see https://github.com/chalk/supports-color/blob/master/index.js#L37-L42)
This PR carries the current color level through to the forked processes
so if they log output that is colorized it will remain so with the same
fidelity of colors as the parent ava process.
