Hi @namanb009,

That is a really cool and useful feature! See below my comment.

• Can you move this function from fury.utils to fury.colormap ?
• Can you add some unittests? look at https://github.com/fury-gl/fury/blob/master/fury/tests/test_colormap.py#L11

Thank you

@skoudoro The utils.py file in this branch just went missing, I don't know-how. So I added it again on my own and now I'm stuck
Can you help me out here?

Hi @namanb009,

it looks like you renamed utils.py to colormap.py. What you should do is:

• go to the folder where there is setup.py
• git remove colormap.py
• cd fury
• git checkout utils.py
• git push

and you should be ok
