I am trying to write a very simple join on select

SELECT *
FROM (
    SELECT *
    FROM (VALUES ('Red'), ('Blue'), ('Green'), ('Yellow')) AS t (colors1)
) A
LEFT JOIN (
    SELECT *
    FROM (VALUES ('Red'), ('Blue'), ('Green'), ('Yellow')) AS t (colors2)
) B ON true

What I would like it to do, is return two columns:

Red Red
Blue Blue
Green Green
Yellow Yellow

But instead it returns each one on the left with each one on the right

Red Red
Red Blue
Red Green
Red Yellow (etc)
