title: I want to add some variation to the colours of my sprites in unity
body: <p>I tried to add some variation to the colour of each sprite using the following code:</p>
  <pre><code>spriterenderer.color = colour+ new Color32(Convert.ToByte(rnd.Next(-10,10)), Convert.ToByte(rnd.Next(-10, 10)), Convert.ToByte(rnd.Next(-10, 10)),255);
  </code></pre>
  <p>This did not work, what way should I do this?</p>
