Highlight dates in a calendar based on event category

Hello. I have a spreadsheet that highlights dates in a calendar based on the event category, but I have only figured out how to do it with each category in a different column (see sheet 'Columns').

What I need to have is the same information but in a list and have conditional fomatting be able to choose the color based on the category entered in one column next to the event date (see sheet 'List'). I have spent hours trying to find something to help me figure this out and I'm just stuck. Please help me.

Highlighting Dates in a Calendar.xlsx

With the range B2:H33 selected use this formula for the CF

=VLOOKUP(B2,$J:$K,2,0)="Board / Shareholder Dates" format as required

repeat for the other 6

That worked perfectly and will save me so much time! Thanks so much!!

You're welcome.
