 1 public Slider slider;
 2 public Image bg;
 3 const int W = 256;
 4 const int H = 256;
 5 void Start () {
 6         var hueTex = new Texture2D(256, 256);
 7         var color = Color.red;
 8         for (int w = 0; w < W; w++)
 9         {
10             for (int h = 0; h < H; h++)
11             {
12                 hueTex.SetPixel(w,h,color);
13             }
14             if (w % 30 == 0)
15             {
16                 color = new Color(Random.Range(0, 255) / 255f, Random.Range(0, 255) / 255f, Random.Range(1, 255) / 255f, 1);
17             }
18         }
19         hueTex.Apply();
20         bg.sprite = Sprite.Create(hueTex, new Rect(0, 0, W, H), Vector2.zero * 0.5f);
21 }
