Unity3D manually code the color

So you can set the Color as below

newanimal.renderer.material.color = Color.white;

but if you want more accurate color you can go to below website to get the red, green, blue

let say you want the chocolate, you get (184,134,11)
but in unity the color is between 0 and 1, so you need to divide the color you found by 256.0, as below


newanimal.renderer.material.color = Color(184/256.0, 134/256.0, 11/256.0);
