暖色与冷色水彩：海上的城市
学习完暖色与冷色知识后，我们创作了这些风景画。
本绘画练习有助于全面掌握仅用水彩调和即可呈现丰富暖色与冷色的多种可能性。
要完成这幅暖色与冷色水彩画，你需要准备：
– 绘画纸
– 铅笔与直尺
– 油画棒
– 水彩颜料与画笔
– 黑色卡纸
– 剪刀与胶水
首先，在绘画纸中央画一条横线，作为你风景画的地平线。
在地平线上方画一个小小的太阳，并画出10–12条波浪线（部分相互交叉），保持整体呈水平走向（代表天空）。
在地平线下方再画出10–12条波浪线（同样部分相互交叉），但整体呈垂直走向（代表海面）。
接着用油画棒沿原有线条重描一遍：天空部分使用暖色，海面部分使用冷色。
这些油画棒线条将形成防水轮廓，防止后续水彩晕染越界。
你可对每个区域分别上色——以清水调和水彩颜料进行晕染，并尝试不同色彩的混合，以获得丰富色相。
待水彩画面自然晾干期间，用铅笔在黑色卡纸上勾勒出天际线轮廓，再用美工刀或剪刀将其裁剪下来。
待整幅水彩画彻底干燥后，将黑色天际线剪贴于画面正中央；注意务必精准贴合在地平线上，确保其完全水平。
Warm & cool watercolor: cities on the sea
After the lesson about warm and cool colors, we made these landscapes.
This painting is useful to learn all the possibilities of creating a wide range of warm and cool colors, just mixing watercolors.
To realize this painting with warm and cool colors, you need:
– drawing sheet
– pencil and ruler
– oil pastels
– watercolors and paintbrush
– black cardboard
– scissors and glue
You start drawing a line in the middle of a drawing sheet, that will be the horizon of your landscape.
On the top you draw a little sun and 10-12 wavy lines, some of them intersected, maintaining a horizontal layout (for the sky).
Underneath you draw other 10-12 intersected wavy lines, with a vertical layout (for the sea).
You redraw the lines with oil pastels, using warm colors for the sky and cool colors for the sea.
These lines will be a water-resistant contour for the watercolours.
You can paint every area blending the watercolours with water, and combining them in different hues.
While the watercolour is drying out, you draw the skyline with a pencil on the black cardboard, and then you cut it out with cutter or scissors.
When the painting is completely dry you paste the black skyline in the middle of your landscape: be careful to past it on the horizon, perfectly horizontal.
