This quick reference guide presents the core formulas, theorems, and compositional rules that underpin artistic practice in the WJEC Year 11 Art and Design curriculum. From colour mixing and perspective to proportion and balance, these foundational principles will support your coursework, sketchbook annotations, and examination preparation. Each rule is broken down into digestible visual and numerical relationships that you can apply directly to your artwork.
本速查手册呈现了支撑 WJEC Year 11 艺术与设计课程的核心公式、定理和构图规则。从色彩混合和透视到比例与平衡，这些基础原则将助力你的课程学习、素描本注释和考试准备。每条规则都被分解为可直接应用于艺术作品的可视化和数值关系。
1. Primary Colour Mixing Equations | 原色混合公式
All secondary and tertiary colours are derived from the three primary colours: red, yellow, and blue. The basic mixing equations are:
所有间色和复色都源自三原色：红、黄、蓝。基本的混合公式为：
Red + Yellow = Orange
红 + 黄 = 橙
Yellow + Blue = Green
黄 + 蓝 = 绿
Blue + Red = Violet
蓝 + 红 = 紫
Tertiary colours are formed by mixing a primary with an adjacent secondary, producing hues such as red‑orange (vermilion), yellow‑orange (amber), yellow‑green (chartreuse), blue‑green (teal), blue‑violet (indigo), and red‑violet (magenta). These equations can be expressed as:
复色由原色与相邻间色混合形成，产出色调如红橙（朱红）、黄橙（琥珀）、黄绿（黄绿）、蓝绿（青绿）、蓝紫（靛蓝）和红紫（品红）。这些公式可表示为：
Red + Orange = Red‑Orange
红 + 橙 = 红橙
Yellow + Orange = Yellow‑Orange
黄 + 橙 = 黄橙
Yellow + Green = Yellow‑Green
黄 + 绿 = 黄绿
Blue + Green = Blue‑Green
蓝 + 绿 = 蓝绿
Blue + Violet = Blue‑Violet
蓝 + 紫 = 蓝紫
Red + Violet = Red‑Violet
红 + 紫 = 红紫
2. Complementary Colour Theorem | 补色定理
Complementary colours sit opposite each other on the colour wheel. When placed side by side, they create maximum contrast and intensify one another. When mixed, they neutralise to a grey or brown. The formula for finding a direct complement is to add or subtract 180° on a 360° colour wheel:
互补色在色轮上彼此相对。并置时，它们产生最大对比并相互增强。混合时，
