如何根据 Google 表格中的条件格式列表为单元格着色

Question

So I'm trying to make a few different lists with different colors and then I want google sheets color automatically whatever is on the list when it's shown elsewhere. I've been trying a few different ways and found a solution that kind of works but isn't really scalable.

I'm bad at explaining things, so hopefully this example does a greater job on that than I did Here's example sheet

Answer 1

yellow list:

=REGEXMATCH(G3, TEXTJOIN("|", 1, $B:$B))

green list:

=REGEXMATCH(G3, TEXTJOIN("|", 1, $C:$C))

blue list:

=REGEXMATCH(G3, TEXTJOIN("|", 1, $D:$D))

red list:

=REGEXMATCH(G3, TEXTJOIN("|", 1, $E:$E))

UPDATE

catfish fix:

=REGEXMATCH(LOWER(G3), LOWER("^"&TEXTJOIN("$|^", 1, $B:$B)&"$"))
