Conditional Formatting - Format one cell based off of text from other cells

New guy here, thanks in advance for any help.

I'm trying to get a cell formatted for color, based off if the text matches a range of cells from another worksheet.

Example:

Cells A2:A6 in sheet Results are as follows:
ARI
IND
BAL
SD
NYJ
OAK

I want cell B2 in sheet Picks to be filled in Green if any of the choices from A2:A6 are there. If not, it should be filled in red.

Any ideas? Is there one formula that can encompass all the choices or to I have to have one rule per possible result?

Use following CF in cell B2

for the green condtion and

for the red one

You could also just color the cells red, and just use 1 CF rule to change them green?
