Animated video for an eyeglass product

Hi, we would like to create a video showing an eyeglass in which the lenses change colors. The project is as follows: 1. Using 1 model of frames, the lenses need to change colors 2. Several color changes are needed, to render 3 videos Video one: The lens starts 'clear', meaning transparent and they darken to become a sunglass. Must show the darkening process by going from clear to dark (with shades in between) . This version is needed in 4 colors, Clear-to-Grey, Clear-to-Brown, Clear-to-Blue, Clear-to-Reddish Video two: The lens starts with a hint of color (think of a very light almost transperent color) and darkenss to become a sunglass. This version is needed in 6 permuations. Ligh-Blue-to-Dark-Blue, Light-Green-to-Dark-Green, Light-Brown-to-Dark-Brown as well as starting with a gradient shade of Light-Blue to darken to solid Blue, starting with a gradient shade of Light-Brown to darken to solid Brown, starting with a gradient shade of Light-Pink to darken to solid red. Video Three: will show the lens as if the wearer was seeing out of it on 3 different background (Golf, Cycling and Snow) on each the area that is seen out of the lens show colors more crips and vibrant, outside of the frame the colors of the background are dull and faded. Each enviorment will have its own color lens, for Golf, lens turns from a ligh-brown to a darker brown, from cycling lens start light-grey and turn dark grey and for snow lens starts light blue and turns deep blue. The 3 videos must be by Friday March 3rd no later than noon CET (Rome) time. All rights for video and ownership must be transfer to us as condition of project assigment.
