Finally, we summarise the findings from our study. We start with a comparison of the frequencies of particular colours with those in the work of other poets and in non-literary texts. We then go on to summarise the use of colours in Thomas’s poetry with reference to the associations postulated in colour studies, and especially how the predominance of green, black and white relates to the great themes in Thomas’s poetry, in particular those of life and death. In conclusion, we state the following: “To conclude, the approach we have taken in this study has in the first place provided the data on the basis of which further interpretative literary analysis can be carried out. In addition, it has laid bare the ways in which Thomas uses colours with their prototypical emotional associations and symbolism to create images which are strikingly potent. The cultural associations and emotional connotations of colours are pervasively present in the poems, and once we understand their workings, the collocations become much less obscure than they appear to be at the first encounter”.
