I've created NSWindow and made it's background colour absolutely blue (#0000FF). But when the window is rendered, the colour is "lighter" than it should be (#0F3FFB).
我创建了NSWindow并将其背景颜色设置为绝对蓝色(#0000FF)。但是当窗口被渲染时，颜色比它应该的要“浅”(#0F3FFB)。
class LilWindow: NSViewController {
override func viewDidLoad() {
self.view.window?.backgroundColor =
NSColor.init(red: 0, green: 0, blue: 1, alpha: 1)
}
Does anyone know why it is happening and how to fix this? (screenshot attached)
有人知道为什么会发生这种情况吗?(附截图)

Okay, so after a couple of hours fiddling with code and @KenThomases help, I figured out that if you want your RGB colours to looks correctly on NSImages and NSWindows, you must convert it into NSDeviceRGBColorSpace colorspace. To do this I've written a simple function:
经过几个小时的代码修改和@KenThomases的帮助，我发现如果你想让RGB颜色在NSImages和NSWindows上看起来正确，你必须把它转换成NSDeviceRGBColorSpace。为此，我写了一个简单的函数:
func toScreenColor(color:NSColor) -> NSColor {
var red: CGFloat = 0, green: CGFloat = 0, blue: CGFloat = 0, alpha: CGFloat = 0
color
.colorUsingColorSpaceName(NSCalibratedRGBColorSpace)!
.getRed(&red, green: &green, blue: &blue, alpha: &alpha)
return NSColor(deviceRed: red, green: green, blue: blue, alpha: alpha)
}
