![颜色代码转换](https://codebeautify.org/img/cb/HEXToCMYKColor.png) # 1. HTML颜色代码基础** HTML颜色代码是用于在网页中指定颜色的十六进制代码。这些代码由六位数字组成,表示红色、绿色和蓝色(RGB)三个通道的强度。例如,代码“#FF0000”表示纯红色,而代码“#FFFFFF”表示纯白色。 HTML颜色代码的格式为:`#RRGGBB`,其中: * `RR`:红色通道的强度,范围为 00 到 FF * `GG`:绿色通道的强度,范围为 00 到 FF * `BB`:蓝色通道的强度,范围为 00 到 FF # 2. 颜色模型和配色方案 ### 2.1 RGB和CMYK颜色模型 #### 2.1.1 RGB模型的原理和应用 RGB(Red、Green、Blue)颜色模型是一种基于加色原理的颜色模型,它通过将红、绿、蓝三原色以不同的比例混合来创建各种颜色。RGB模型主要用于显示器、电视和计算机屏幕等电子设备中。 **代码块:** ``` // RGB颜色值表示 const rgbColor = "rgb(255, 0, 0)"; // 红色 const rgbColor = "rgb(0, 255, 0)"; // 绿色 const rgbColor = "rgb(0, 0, 255)"; // 蓝色 ``` **逻辑分析:** 上述代码块展示了RGB颜色值的表示方式。每个颜色值由三个数字组成,分别表示红色、绿色和蓝色的强度,范围从0到255。例如,"rgb(255, 0, 0)"表示纯红色,因为红色分量为255,而绿色和蓝色分量为0。 #### 2.1.2 CMYK模型的原理和应用 CMYK(Cyan、Magenta、Yellow、Key Black)颜色模型是一种基于减色原理的颜色模型,它通过将青色、品红色、黄色和黑色四种油墨以不同的比例混合来创建各种颜色。CMYK模型主要用于印刷和出版行业。 **代码块:** ``` // CMYK颜色值表示 const cmykColor = "cmyk(0, 100, 100, 0)"; // 青色 const cmykColor = "cmyk(100, 0, 100, 0)"; // 品红色 const cmykColor = "cmyk(100, 100, 0, 0)"; // 黄色 const cmykColor = "cmyk(0, 0, 0, 100)"; // 黑色 ``` **逻辑分析:** 与RGB模型类似,CMYK颜色值也由四个数字组成,分别表示青色、品红色、黄色和黑色的强度,范围从0到100。例如,"cmyk(0, 100, 100, 0)"表示纯青色,因为青色分量为100,而其他三个分量为0。 ### 2.2 配色方案的理论和实践 #### 2.2.1 色彩和谐的原则 色彩和谐是指不同颜色组合在一起时产生的视觉美感。有几种色彩和谐的原则,包括: - **互补色:**颜色环上相对的颜色,如红色和绿色、蓝色和橙色。 - **类似色:**颜色环上相邻的颜色,如蓝色、蓝绿色和绿色。 - **单色:**同一颜色的不同色调,如深蓝色、蓝色和浅蓝色。 - **三合色:**颜色环上等距的三个颜色,如红色、黄色和蓝色。 #### 2.2.2 常用配色方案和应用场景 基于色彩和谐的原则,有许多常用的配色方案,如: | 配色方案 |
