I think that in continuing with the theme of hybrid/synthetic weather I can alter the color of the cloud, but only in natural shades. In this way I am creating the illusion of a natural cloud at a time that it would not appear that way. For instance, one fluffy white cloud on a cloudless day, or a angry cloud on a otherwise nice day. Conversely, if the whole sky is hazy and gray, the cloud can be pristine white. It calls into question the naturality of the cloud that i am making, and presents it as something that is both a part of the weather, but under different control. I can light the cloud very bright white, as a utopian cloud, or dark grey/ green as a stormy angry cloud. It can even be bright white in the middle of the night!
