Each square contains the logo along with colored squares of each color so you can see how they all work together as a whole. The strength of the bottom option is that the colors progress and transition easily into one another smooth and orderly whereas the top logo color palette is nice too - but it is a little more "jumpy" that the smooth transitions of the bottom color palette. That said, life is seldom smooth and is more of an ordered chaos at best anyway - so the top color palette may be closer to the message you are trying to convey.
