As a public service, how about some Matisse?
Young Woman at The Window Sunset, 1921

Matisse, The Silence That Lives in Houses, 1947

Don't you feel better?
Matisse, Girls in a Yellow and Red Interior ,1947

We can debate important issues like flowers:
Matisse, Anemones and Chinese Vase, 1922

Matisse is the antidote.
Henri Matisse
Bonheur de Vivre - Joy of life, 1906

For the next debate we can have a mimosa-off:
Moise Kisling, Acacia/Mimosas, 1939
or
Pierre Bonnard, Mimosa. - 1915

Or a cherry-blossom-off
Kasamatsu Shiro (笠松紫浪) Shinobazu ike, View through the cherry blossom at dusk. Woodblock Print, Japan, 1932
or
Hennie De Korte (Netherlands b.1941)
Still life with Cherry Blossom Branches and Vessels

The moderator should have asked:
Who dahliad better, Mondrian or Nolde?
Piet Mondrian, Red Dahlia, 1907. Watercolor
Emil Nolde,Dahlias in a Yellow Vase (1930-1939)
watercolor

An O'Keeffe can cleanse any evil.
Georgia O'Keeffe, Red Poppy, No. VI, 1928

Redon is more effective than air freshener.
Too beautiful:
Odilon Redon, "Flowers: Poppies and Daisies"; oil on cardboard [c.1867]

And a Fantin-Latour before bed
Henri Fantin-Latour, Lilacs, 1872

And a blessing, one of my all times favorites:
Odilon Redon - Nocturne, huile sur carton, 18 x 23,4 cm
Goodnight, all. May your dreams be not troubled.
