📖 简介
基于 React + Tailwind CSS 构建的专业颜色转换工具，支持多种颜色格式的实时转换。无论是设计师、开发者，都能在这个工具中找到所需的颜色转换功能。
✨ 核心功能
🎯 多格式颜色转换
- HEX 格式: 支持 3 位缩写 (
#000,#fff) 和 6 位完整格式 (#ff6b6b) - RGB/RGBA: 红绿蓝颜色空间，支持透明度
- HSL/HSLA: 色相饱和度亮度，更直观的颜色表示
- HSV: 色相饱和度明度，常用于图像处理
- CMYK: 青品黄黑，印刷行业标准
🌟 亮点
全面的颜色空间支持
// 支持的颜色格式示例
#ff6b6b // HEX 6位
#f66 // HEX 3位缩写
rgb(255, 107, 107) // RGB
rgba(255, 107, 107, 0.8) // RGBA
hsl(0, 100%, 71%) // HSL
hsla(0, 100%, 71%, 0.8) // HSLA
hsv(0, 58%, 100%) // HSV
cmyk(0%, 58%, 58%, 0%) // CMYK🎯 使用场景
- CSS 开发: 快速获取不同格式的颜色值用于样式开发
- 主题系统: 构建多主题应用时的颜色格式转换
- 调试工具: 快速验证和转换颜色值
💻 核心代码实现
1. HEX 到 RGB 转换（支持缩写）
const hexToRgb = (hex) => {// 支持 3 位 HEX 缩写，如 #000, #fffif (/^#?([a-f\d])([a-f\d])([a-f\d])$/i.test(hex)) {const result = /^#?([a-f\d])([a-f\d])([a-f\d])$/i.exec(hex);return {r: parseInt(result[1] + result[1], 16),g: parseInt(result[2] + result[2], 16),b: parseInt(result[3] + result[3], 16),};}// 支持 6 位 HEX，如 #000000, #ffffffconst result = /^#?([a-f\d]{2})([a-f\d]{2})([a-f\d]{2})$/i.exec(hex);return result? {r: parseInt(result[1], 16),g: parseInt(result[2], 16),b: parseInt(result[3], 16),}: null;
};2. RGB 到 HEX 转换
const rgbToHex = (r, g, b) => {return "#" + ((1 << 24) + (r << 16) + (g << 8) + b).toString(16).slice(1);
};3. RGB 到 HSL 转换
const rgbToHsl = (r, g, b) => {r /= 255;g /= 255;b /= 255;const max = Math.max(r, g, b);const min = Math.min(r, g, b);let h,s,l = (max + min) / 2;if (max === min) {h = s = 0;} else {const d = max - min;s = l > 0.5 ? d / (2 - max - min) : d / (max + min);switch (max) {case r:h = (g - b) / d + (g < b ? 6 : 0);break;case g:h = (b - r) / d + 2;break;case b:h = (r - g) / d + 4;break;}h /= 6;}return {h: Math.round(h * 360),s: Math.round(s * 100),l: Math.round(l * 100),};
};4. HSL 到 RGB 转换
const hslToRgb = (h, s, l) => {h /= 360;s /= 100;l /= 100;const hue2rgb = (p, q, t) => {if (t < 0) t += 1;if (t > 1) t -= 1;if (t < 1 / 6) return p + (q - p) * 6 * t;if (t < 1 / 2) return q;if (t < 2 / 3) return p + (q - p) * (2 / 3 - t) * 6;return p;};let r, g, b;if (s === 0) {r = g = b = l;} else {const q = l < 0.5 ? l * (1 + s) : l + s - l * s;const p = 2 * l - q;r = hue2rgb(p, q, h + 1 / 3);g = hue2rgb(p, q, h);b = hue2rgb(p, q, h - 1 / 3);}return {r: Math.round(r * 255),g: Math.round(g * 255),b: Math.round(b * 255),};
};5. RGB 到 HSV 转换
const rgbToHsv = (r, g, b) => {r /= 255;g /= 255;b /= 255;const max = Math.max(r, g, b);const min = Math.min(r, g, b);const d = max - min;let h,s,v = max;s = max === 0 ? 0 : d / max;if (max === min) {h = 0;} else {switch (max) {case r:h = (g - b) / d + (g < b ? 6 : 0);break;case g:h = (b - r) / d + 2;break;case b:h = (r - g) / d + 4;break;}h /= 6;}return {h: Math.round(h * 360),s: Math.round(s * 100),v: Math.round(v * 100),};
};6. RGB 到 CMYK 转换
const rgbToCmyk = (r, g, b) => {r /= 255;g /= 255;b /= 255;const k = 1 - Math.max(r, g, b);const c = (1 - r - k) / (1 - k);const m = (1 - g - k) / (1 - k);const y = (1 - b - k) / (1 - k);return {c: Math.round(c * 100),m: Math.round(m * 100),y: Math.round(y * 100),k: Math.round(k * 100),};
