Description

Using --colormap NAME from the CLI, with any of the supported colormap names does not seem to have any impact on the result.

Steps/Code to Reproduce

All these CLI calls produce the same result:

wordcloud_cli \
  --text tmp/debug.txt --random_state 1 \
  --imagefile 1.png --colormap Greens

wordcloud_cli \
  --text tmp/debug.txt --random_state 1 \
  --imagefile 2.png --colormap hot

wordcloud_cli \
  --text tmp/debug.txt --random_state 1 \
  --imagefile 3.png --colormap binary

Expected Results

Expected to see different colors.

Actual Results

All calls use the same default colormap.
