Fix for selected index when switching scale

[pavelkeyzik]

This PR fixes the issue #19.

I've updated the code to check if our selected index is greater than our color scale, and if it is, then we just select the last color from the scale, but if we switch back, it will be the same selected color.

@rafaeltab Could you test it and let me know if everything works as expected? 😊

I want to but I need to join Cole Bemis's before I can. I have requested access.

Oh... Sorry! I've just realized that to test it we need the access 😄 Maybe Cole Bemis will came up with something that will allow us to test it.

We actually switched from Netlify to GitHub Pages for deploys (still need to remove the Netlify integration 😅). I'll chat with @rezrah about how we can let contributors deploy previews of the app.
