I have made this PR with the first changes that I felt should be made.

1. The function rgbToHex() is going unused, but I haven't currently removed it (waiting for your suggestion on it).
2. The functions lighten and darken, clash with the current code functions and hence I have currently made alias for the published package functions.

As I was not sure with my changes, I am awaiting your suggestions on them. Finally if required I will rebase these multiple commits and keep 1 final commit having correct changes.

Thanks for the contribution @SohamRatnaparkhi - I actually have no clue why this doesnt work. I really expected it work better than my hacky functions :P
