Reuse custom color in ThemeData

I have a class for declaring custom colors.

class CustomColors {
static const Color myCustomBlack = const Color(0x8A000000);
}

My question is: Why I can not use them in Theme data as follows?

ThemeData(primarySwatch : CustomColors.myCustomBlack)

primarySwatch isn't a normal Color, it is a MaterialColor, so you can't assign any Color to it. And a MaterialColor is the one which has shades like 100, 200, ... 900.

For example:

Colors.blue is a MaterialColor as you can use shades like Colors.blue[100] and Colors.black isn't a MaterialColor, you get error on using Colors.black[100].
