互补色的心形

互补色因其强烈对比而格外迷人：两种对比色之间充满张力的“对抗”，由光、亮度与能量共同构成。我们通过将一个图形及其背景分别涂上互补色，验证了这一点。
我是在Artsonia美术馆网站上发现这一活动的，认为它非常适合借以复习互补色的相关理论知识。
所需材料如下：

• A4尺寸的绘图纸或白卡纸
• 直尺、铅笔、橡皮
• 水彩颜料及画笔
• 彩铅
• 剪刀和胶水
• 一张A4尺寸的纸

首先，在绘图纸背面进行构图：用直尺将纸面均分为6个矩形（10.5 cm × 9.9 cm），并在每个矩形中心画一颗心形。注意使6颗心形的位置、形状与大小基本一致。

接着，沿垂直线将纸张裁开，得到两条长条：其中一侧为白色，另一侧则印有心形图案。
现在，用单一颜色（如蓝色）的不同明度色调，将第一条长条的白色面完整自由地涂满；再用其互补色（如橙色）的不同明度色调，将第二条长条同样完整自由地涂满。

待水彩干透后，用彩铅在已着色的表面绘制若干形状、线条与图案——所选彩铅颜色应与底色相近，并让新绘图形与原有色彩层叠交错。

随后，将已上色的长条翻转过来，沿轮廓剪下各矩形及其中的心形。最后，将剪下的矩形与心形粘贴到另一张A4纸上，注意交替使用互补色进行拼贴组合。

Hearts in complementary colors

Complementary colors are fascinating because of their contrast: the powerful fight between two contrasting colors is made of light, brightness and energy. We proved it painting a shape and its background in complementary colors.
I found this activity here in Artsonia Art Museum and I thought it was a good idea to review the theory about complementary colors with this activity.
We need:

• drawing paper or white cardboard size A4
• ruler, pencil, rubber
• watercolors and paintbrushes
• colored pencils
• scissor and glue
• a sheet of paper size A4

First we prepare a drawing on the rear of the drawing sheet: with the ruler we divide the sheet in 6 rectangles (10,5 cm x 9,9 cm) and in the middle of each rectangle we draw a heart. Pay attention to draw the 6 hearts more or less with the same position, shape and size.

After that we cut the sheet alongside the vertical line, in order to obtain two strips:  one side of the strip is white and on the other side there is the drawing of the hearts.
Now we paint the white part of the first strip with different tones of a single color ( e.g. blue), and then we paint the second strip  with different tones of the complementary color (e.g. orange). We paint the surface completely and freely.

When the watercolors are dry, we draw on the colored surface some shapes, lines and patterns in the similar colors of the background, overlapping new drawings with colored crayons.

Then we turn over the colored stripes and cut out the rectangles and the hearts with a scissor. At the end we paste the rectangles and the hearts that had been cut out, on another sheet of paper, paying attention to glue the shapes with alternate complementary colors.
