铜锈的颜色多为粉绿色或者浅蓝色，可根据底色需要调整冷暖关系。铜锈多产生于地点处，可用小笔点色在凹点处，也可以把调好的颜色淋在做好底色的雕像上，然后用布擦去高点处的铜锈色，这种方法做出来的效果很自然，也是仿铜效果中提神和画龙点睛的一步。
The color of copper rust is mostly pink-green or light blue. The relationship between cold and warm can be adjusted according to the need of background color. Copper rust mostly occurs in the place, can be used to dot the concave point with a small brush, can also be tuned to the color of the sculpture on the ground, and then wipe off the copper rust at the high point with a cloth, this method is very natural, but also a step to refresh and draw the finishing touches of the imitation copper effect.
