如何使用红色、绿色和蓝色值创建颜色？
提问于 2021-09-24 07:40:34
我正在尝试使用RGB值创建一个颜色，但是我得到了以下错误。我无法找到解决办法。
Color(148f, 148f, 148f, 1f)以下是我遇到的错误：
java.lang.IllegalArgumentException: red = 148.0, green = 148.0, blue = 148.0, alpha = 1.0 outside the range for sRGB IEC61966-2.1 (id=0, model=Rgb)

您需要使用ColorSpaces.Srgb来指定0.255范围内的值。这里的文档中有一个非常好的表：https://developer.android.google.cn/reference/kotlin/androidx/compose/ui/graphics/Color
所以基本上你应该用它
Color(red = 148f, green = 148f, blue = 148f, alpha = 1f, ColorSpace.get(ColorSpaces.Srgb))页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
