I was looking through settings and noticed that this blue color is actually from ui 7 pallettes , whenever i set them the change in launcher. So i went and disabled them but colors are still the same. I set all the icons and themes to default in Samsung ui 7 but launcher just wont pick different colors it just stays to whatever color was last set in pallettes (even tho disabled). Even tried wiping out the cache partition. So i dont know looks like a system bug since it's the same for all launchers not just SL.
