@eata219 what's the benifits? thanks so much.

As described in #467 , the result of --output dyff is not colorized when helm-diff process is piped.

You can reproduce this by helm diff --output dyff .... | less -R .
Also using helmfile, the result of helmfile diff --output dyff ... is not colorized.

Using less is useful when the output is long.
Also helmfile is useful tool for deploying many charts.

This PR will colorize the result of dyff output in above situations.

Does this error randomly occur? Cloud you retry it?
