I think maybe he wants to filter a list based on some function, like floor. Not sure how to do this. Can you not just do floor([1.1,2.1,3.1])?

What I was trying to say was how could I remove one list from another list.

I was also trying to translate a list into a list of colors (kind of like this), but I think I could figure it out myself.

Thank you for your help!
