Color cannot be used from multiple goroutines safely

[ashrwin]

Color uses the fmt package which is not safe to be used across multiple concurrent goroutines.
We need to either

• Use log package, which is safe to be used across multiple goroutines
• Add a mutex

Hi @ashrko619 This is ok. You should assume that all libraries/package are not safe by default (unless it's stated in the document). I do not state it and I don't want it to be that way. This should be used just like any other library, so it's the users responsibility to guard it. Thanks
