如何在UIColor中获得随机的冷/暖颜色？

// 生成随机的冷/暖颜色
func getRandomColor() -> UIColor {
    let randomValue = CGFloat(arc4random_uniform(256)) / 255.0 // 生成0到1之间的随机数
    
    // 生成冷色调
    let red = randomValue
    let green = randomValue
    let blue = 1.0 - randomValue
    
    // 生成暖色调
    // let red = 1.0 - randomValue
    // let green = randomValue
    // let blue = randomValue
    
    return UIColor(red: red, green: green, blue: blue, alpha: 1.0)
}

// 使用示例
let randomColor = getRandomColor()

// 输出颜色的RGB值
var red: CGFloat = 0
var green: CGFloat = 0
var blue: CGFloat = 0
randomColor.getRed(&red, green: &green, blue: &blue, alpha: nil)
print("Red: \(red), Green: \(green), Blue: \(blue)")
