        at com.chrynan.colors.BaseRgbaColor.<init>(BaseRgbaColor.kt:13)
        at com.chrynan.colors.BaseRgbaColor.<init>(Unknown Source:0)
        at com.chrynan.colors.ColorConstructorUtilsKt.RgbaColor(ColorConstructorUtils.kt:245)
        at com.chrynan.colors.ColorUtilsKt.lerp(ColorUtils.kt:103)

To Reproduce

• Invoke this function

fun test(color: Long): Color {
   return lerp(Color(color), Color.White, 50.0)
}
