You can see a demo here of what I could get Playground
please note at actual code, Im using randomColor like this.
/// https://github.com/davidmerfield/randomColor
const [r,g,b] = randomColor({luminosity: 'light', hue: 'red', format: 'rgbArray'})
const color = Color3.FromInts(r,g,b)//where in playground I used Color3.Random()
