You are now in a research process in which you want to experiment with fragments that can be put in different compositions. You are also thinking about the choice of colour in the relation to the organic shapes. And in relation to that you want to try out in the best possible space. You want to find the best way to use colour. You want to try out some things. You get advice from your studio teachers.  I suggested to make notes from this research. On the basis of notes, advises (from teachers) and pictures, and your reflections on the questions if something worked or not (after you tried it out), you could make your essay. You could add to this research theories about colour (see post 1 for suggestions).
