RGB values to an image

[Bhag]

Hi,
I have a data set which contains RGB values. The RGB colours are clustered as 1,2,3 and 4. The file is like this.
R G B Cluster
12 2 123 1
23 32 45 1
21 56 45 2
12 57 87 2
....

I want to display these data according to the clusters like yellow color for cluster 1, Black for cluster 2 and so on. Could you please tell me how to do this in Python?

Create a dictionary with the cluster numbers as keys and the display colors as corresponding values as in

colorDict = {1: "Yellow", 2: "Green")
