How to change default radio button color

A very gentle question.

This code:

local radioButton1 = widget.newSwitch(
    {
        width = bla,
        height = bla-bla,
        style = "radio",
        id = "RadioButton1",
        initialSwitchState = true,
        onPress = onSwitchPress
    }
)

makes a blue radio button:

Help, please, to change the color!

I don’t know if there is any other way but looking at the docs, only way seems to be through image sheets. Here: https://docs.coronalabs.com/api/library/widget/newSwitch.html#visual-customization

(Keep in mind that widget library can be found here: https://github.com/coronalabs/framework-widget/tree/9c1aed5838704a5b0184130c2bf4691f7c163f56 . You can make changes to fit your needs.)

@bgmadclown, thank you very much.
