I suppose you could create a function, use a cursor to walk through the table row by row, assign the result of the each row fetched to the same variable each time.

CREATE FUNCTION returns text
DECLARE
a text;
single_row text;

BEGIN

FETCH CURSOR INTO

a := SELECT COLOR FROM X;

single_row := single_row || ':' || a;

LOOP;

END;

return single_row;
