Colors shades are rendering incorrectly

[jxnblk]

After one of the recent changes, the returned color arrays are not behaving as expected

@jxnblk what's up with the arrays? I've been tearing your library apart at work recently so I'm quite familiar with it by now, maybe I can help you?

If you're interested here's my code: https://github.com/braposo/palx/blob/custom-luminance/src/index.js

I've made some changes like:

• adding the decimal of the base colour instead of always .5 in the luminance calculation so the base colour is always one of the shades.
• generating the shades for the other hues by first generating the base colour shades from the luminance steps, but then just rotating the hues and locking the saturation and lightness from each of the base shades. I felt it gave us more consistent results than using the luminance again for the other hues. Is that the problem you're seeing?
• added an extra row of 5 selected shades for each colour but that's really just for us so please ignore that part

The code is quite rough, I've been playing with it in the design team but want to clean it and make it more usable by others in the future.

@braposo did you create a PR for this?
