Oh blue, such a lovely colour, a colour that prides itself in standing out, blue doesn't beg to look beautiful, it just suits and blends so well with all that is good...yes now i see a blue sun in your post, it got me actually wishing for a beautiful blue sun, pictures will be more beautiful and the heat will be mild, it will be so good, since yiu said the plant needs the yellow sun so how about, blue sun once a week. Such a beautiful imagination...
