Working with Color 色彩運用Ditch hex for HSL 放棄十六進位制,轉用HSLYou need more colors than you think 你需要的顏色比想象中更多Define your shades up front 預先定義色階Don't let lightness kill your saturation 不要讓亮度影響飽和度Greys don't have to be grey 灰不一定選純灰Accessible doesn't have to mean ugly 無障礙設計不等於醜Don't rely on color alone 不要僅僅依賴顏色
