To paint an autumn landscape I will not try to remember what colors suit this season, I will only be inspired by the sensation that the season gives me; the icy clearness of the sour blue sky will express the season just as well as the tonalities of the leaves. My sensation itself may vary, the autumn may be soft and warm like a protracted summer or quite cool with a cold sky and lemon yellow trees that give a chilly impression and announce winter.
