Colors in console does not work

I am printing an images in terminal with node script and package chalk, but colors is wrong!
Same script works perfectly in CircleCI and local PC.

Travis build: https://travis-ci.org/mrdoob/three.js/jobs/650480517?utm_medium=notification&utm_source=github_status

Very annoying bug, please help! I need to see test results inside travis.
