I have a list and want to know if my column contains any of the lists values.

Hello, I have a table with column colors which has one or many colors as inputs:
Example:

Column : Colors
Row 1  : RED
Row 2  : RED and GREEN
Row 3  : RED and ORANGE
Row 4  : ORANGE
Row 5  : GREEN AND MAGENTA
Row 6  : ORANGE AND BLACK

…..
My colleague gave me a list of 25 unique colors and wants to know if any of these colors are in my table.
I did this:

select 
        colors
        , case when colors like '%GREEN%' then 1
               when colors like '%RED%' then 1
               when colors like '%PURPLE%' then 1
               ...
               else 0
               end found_colors
from        my_table

but you can see that this is not efficient since I had to manually type each like and the colors.
I tries exist but but it has 0 as output for “RED and GREEN”.
I believe there is a better way to do it.
Any suggestions?
BTW I am using pl/sql

Nick
