Palette, Profile, Swatch - need help to understand the terms

[sevar83]

First - thanks for the great library. I need some help to properly understand the terms - palette, proflle and swatch. Ok, palette should be a collection of colors. Profile - a predefined palette. Right? But this swatch thing is quite confusing. What means "RGB swatch" Why exactly RGB? That's a color representation scheme. How's that related to the actual target?
Then this text color...

public PicassoPalette intoTextColor(TextView textView) {
      return this.intoBackground(textView, Swatch.TITLE_TEXT_COLOR);
}

How come setting the text color actually assigns a background or do I miss something!? The library is very useful and it already improved my view appearance a lot. But some more explanations in the docs are needed to get the most of it.
