Dynamic Drop Down List?

Here is what I'm needing to accomplish:

1. In sheet "Colors" I have a list of colors in column A.

2, In sheet "Teams" I want to assign a unique color in column B to each team listed in column A.

3. I want to create a drop down list in each cell of column B to select a color from the list of colors.

4. Then once a particular color is selected in a cell, it should not show as a choice to pick from iwhen you move to the next cells.


Any help would be appreciated!! Thanks!
