Hello @akhilbojedla ,

Thanks for PR.

As library https://github.com/fatih/color is archived on Github and no more maintained by the author, should we use the different library for color?

ex:- https://github.com/logrusorgru/aurora

WDYT?

Hi @gopinath-langote ,

I didn't knew about aurora library. I've replaced https://github.com/fatih/color with https://github.com/logrusorgru/aurora

Let me know if you we need to change anything else.

Do you think checking color in test is worth and necessary - I am ok to just test the output and not colors.

WDYT?

[akhilbojedla]

Yes. But just comparing the text wont assert true when one of it is coloured. I can switch off colour on aurora but Have to initialize a non default aurora instance based on a flag which by the current implementation takes a while to implement.
