I don't think that you can declare SQL variables like this. The
conventional method would be to use a look up table that hold the
cross-reference between integer and color name. You could then change
your view definitional like so:
CREATE VIEW primary_colors_foos AS
SELECT * FROM foo
WHERE color = ANY( SELECT colorid
FROM Colors
WHERE colorname = ANY( 'red', 'blue', 'yellow' ));
