[Feature] Re-implement old color picker + allow to type the color code

[Palloxin]

##Description

The old color picker is better, it had 4 ways to select the colors(loved it), i could type the color code, AND a useful rainbow bar, easy to know which range is what:

Now it's just a shadow of what it was, it's a downgraded version.
