Some colors act weird when the brightness is modified

[helloHackYnow]

I think it's because of the use of module colour.
I think I resolved it in my fork with getting rid of the use of this module.

(I'm new to github so perhaps I did not submit the issue correcly, please forgive me)

@helloHackYnow Yes, this is a issue with the colour module. It generates irrelevent range of colors.
But if you find any other easy way of generating the color ranges, then please do share :)
(Give a PR.)
