Modelling in Quill - tube train

Modelling the tube train in Quill. Played with colours of the doors and windows, as the cream/grey as they would actually be, is either too drab or too stark. There needs to be a definite and individual difference between the visual aesthetic of  the three worlds of the participants. As David's environment has stark white lines against a dark background, to create the idea of negative space, the starkness of the doors and windows of the tube, would have been too similar. By using a dark blue, the elements of the tube, for example doors, windows and structural outline, will still stand out against the electric blue of the tube tunnel tiling, whilst giving a hint of form without being visually overpowering.
