randomLightColor function
Returns a random light color. The mode can be optionally specified, which has to be either 1 (for one-primary) or 2 (for two-primary). Any other value will result in a random mode.
Implementation
Color randomLightColor({int mode = -1}) {
Color dark = RandomColor().getRandomDarkColor();
int r = 255 - dark.red;
int g = 255 - dark.green;
int b = 255 - dark.blue;
return Color.fromARGB(255, r, g, b);
}
