🌈 色彩基礎理論🌈 Color Theory Basics
色彩三要素Three Elements of Color
理解色彩的三個基本屬性是掌握配色的關鍵:Understanding the three basic properties of color is key to mastering color matching:
1️⃣ 色相(Hue)1️⃣ Hue
定義:顏色的基本屬性,即「什麼顏色」(紅、橙、黃、綠、藍、紫)Definition: The basic property of color, i.e., "what color" (red, orange, yellow, green, blue, purple)
在色輪上以 0-360 度表示Represented as 0-360 degrees on the color wheel
高飽和度顏色充滿活力,低飽和度顯得柔和High saturation colors are vibrant, low saturation appears softer
💡 應用:主色用高飽和度吸引注意,背景用低飽和度避免疲勞💡 Application: Use high saturation for primary colors to attract attention, low saturation for backgrounds to avoid fatigue
最常用於網頁設計的顏色格式,簡潔且廣泛支援。The most commonly used color format in web design, concise and widely supported.

色盲友善設計Color Blind Friendly Design
色盲類型與影響Types of Color Blindness & Impact
紅綠色盲:最常見(男性 8%,女性 0.5%),難以區分紅色和綠色Red-green color blindness: Most common (8% males, 0.5% females), difficulty distinguishing red and green
藍黃色盲:較少見,難以區分藍色和黃色Blue-yellow color blindness: Less common, difficulty distinguishing blue and yellow
全色盲:極少見,只能看到灰階Total color blindness: Very rare, can only see grayscale
💡 色盲友善設計技巧💡 Color Blind Friendly Design Tips
不要只依賴顏色:使用圖示、文字、圖案等輔助
例如:❌ 只用紅綠表示錯誤/正確
✅ 使用紅色 + ✘ 圖示 / 綠色 + ✔ 圖示Don't rely on color alone: Use icons, text, patterns as aids
Example: ❌ Using only red/green for error/success
✅ Using red + ✘ icon / green + ✔ icon
使用高對比度:確保即使顏色無法區分,明暗仍可辨識Use high contrast: Ensure light/dark differences remain distinguishable even without color
避免問題組合:Avoid problematic combinations:
紅色 + 綠色Red + Green
藍色 + 紫色Blue + Purple
綠色 + 棕色Green + Brown
使用色盲模擬工具:測試設計在色盲視角下的效果Use color blindness simulators: Test your design from a color blind perspective
