How to create Color using red, green and blue values?

I am trying to create a Color using RGB values but I am getting following error. I am unable to find a solution for it.

Color(148f, 148f, 148f, 1f)

Following is the error I am getting:

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)

I checked the code of the Color class and found that I need to specify ColorSpace but I am unable to find the proper ColorSpace for my requirement.

CodePudding user response：

The constructor you're using expects floats in range 0..1.

Use Int values instead:

Color(148, 148, 148, 255)

CodePudding user response：

You need to use ColorSpaces.Srgb to specify values in 0..255 range. There is a very nice table in documentation here: https://developer.android.google.cn/reference/kotlin/androidx/compose/ui/graphics/Color

So basically you should use it like

Color(red = 148f, green = 148f, blue = 148f, alpha = 1f, ColorSpace.get(ColorSpaces.Srgb))
