The Hoya HD UV filters work in neutral colour and are used to prevent the quality of the photos from being affected by UV rays, which is usually the case with diffuse light or haze These quality reducing UV rays are simply filtered out, only the visible light finds its way to the lens. The result is intense colours and high contrast. UV filters also fulfil another purpose, constantly screwed on the filter protects the front lens of the lens from dirt and damage.
