Color palette with material colors

It would be very convenient to have a set of colors from Material Design in this library which would be used in the common code.

Color palette according to https://www.materialui.co/colors

Usage example:
val green = MaterialPalette.LIGHT_GREEN_500

The approximate vision of implementation:

object MaterialPalette {
    ...
    val LIGHT_GREEN_100 = Color (...)
    ...
    val LIGHT_GREEN_900 = Color (...)
    val LIGHT_GREEN_A100 = Color (...)
    ...
}

Implement unit-tests for extensions functions

now we have some calculations but not check automatically that all calculated correct

Trying to make it work on a new project using KMM plugin

Hi !

I try to make this library work on a new project and I can't get my head around it.

On Android and in the multiplatform library it works like a charm but I cannot get toUIColor() method work on iOS in swift.

I made a sample project demonstrating the issue : https://github.com/nverinaud/SampleMokoGraphics.

Could you please help me make it work ?

It seems like the iOS specific code of the library is not exposed in the resulting multiplatform framework.

Thanks !

get color in hexadecimal form

There is an idea to get the color in hexadecimal format.
For example, I need to use it in URL with colorParameter in format "#RRGGBB"
