There seems to be no shadowing and modelling is poor which makes it difficult to locate one individual light source. It also gives the figures a two dimensional appearance and makes them seem vacant and sombre. The tonal range is wide but the use of cool colours (in particular
greys and blues) has the effect of distancing the spectator from the scene. Furthermore, emphasis is placed on colour rather than detail because the brushwork is crude. These factors lend the scene a cold and somewhat eerie feeling.
Rothko's repeated use of vertical lines (specifically the railings and pillars) segregates the figures from one another and more significantly, from the spectator. The overlapping of these objects gives the scene perspective, but along with the idea of segregation and a high picture plane, this only serves to further distance the spectator.
The two left most pillars are arranged in such a way that they run parallel with the two right most pillars and with the wall at the back left of the scene. Furthermore the figures on the descending staircase and the figures around the ticket booth are along the same parallel plane,
and are framed within the pillars. The effect is that the eye is drawn towards the booth along this line. Perhaps then it is no coincidence that the ticket booth also seems to be the location for the vanishing point. These factors would suggest that the implied spectator position is further back along the same line as the ticket booth and the figures on the descending stairs.
Rothko uses the methods I have discussed to distance and segregate the spectator from the scene. Along with his brushwork, lighting and choice of colours, this lends the painting an eerie atmosphere. As such, Subway Scene is a bleak and cold image that stresses a feeling of alienation to the spectator.
