I tried a few different materials but crepe paper worked best.
I managed to buy a few different shades of different colours so I could fade the colours so it wouldnt be just a single block colour.
I attempted to fill all of the windows in the large stairwell in with either a green or yellow but was unable to get material big enough to cover the window. After some thinking as to how to get around this, I thought about putting a green filter over a photography light and pointing it up through the stairwell so it could be seen fading up through from outside. Unfortunately, powers beyond my control stopped this from happening.. I rented out two lights and neither one of them would work.
If I had more time on this project I would attempt to cover all major windows in the school to give the feel of the colour bursting from all sides of our college.
