Populate boolean if two table values exist in another table

[TeslaBoy]

I know this must be something simple but a little stumped at the moment.

I have 2 tables. Table1 has a bunch of users and their colors. The colors are repeated for each user, so all users have 3 rows. This table was built from a workflow I built.

Table2 is a record of which colors each user has, so the row count for each user is different. This is an imported data source (csv).

I want to populate a third column in Table1 that will be a boolean showing if that user has that color.

I've been Googling for a solution and I can't seem to put it together. In Excel this would be pretty straightforward, just a COUNTIFS, so I'm guessing it's something simple. Thanks for any help!!
