在紅 黃為主色的照片中，埋入以藍為主的色調，是作畫的目的。

. Using concept to build up a bigger space, more depth painting.

. When light blue on sky, yellow and red on bushes/woods, we choose green, secondary color as we want to put on twilight zone, which were designed on lower part of river.

. Using palette knife to smooth and squeeze the painting into the canvas' small cave.

. It will creat 2 layers color on one spot, showing special feeling of light.
