Uniwhite icon set is modified version of Malys-uniblue icon set. Malys had created two versions Uniblue and Uniblack for Linux but those doesn't fit with dark themes, so desm0tes from deviantart moded this icon theme to light-grey color for dark themes. Most of the users like to use dark themes on their desktop because it doesn't effect eyes much as other colors does like white. You can use Unity Tweak Tool, Gnome-tweak-tool or Ubuntu-Tweak to change icons.
