                color = new Color32(0, 0, 0, 255);
                break;
            case 1:
                color = new Color32(255, 255, 255, 255);
                break;
            case 2:
                color = new Color32(255, 0, 0, 255);
                break;
            case 3:
                color = new Color32(0, 255, 0, 255);
                break;
            case 4:
                color = new Color32(0, 0 , 255, 255);
                break;

                color = new Color32(255, 255, 0, 255);
                break;
            case 6:
                color = new Color32(0, 255, 255, 255);
                break;
            case 7:
                color = new Color32(255, 0, 255, 255);
                break;
            case 8:
                color = new Color32(192, 192, 192, 255);
                break;
            case 9:
                color = new Color32(128, 128, 128, 255);
                break;
        }
    }

I dont understand your question fully, but I try to help you.

1. Set your Slider like this. Max value is 10, because you have 10 color. And choose Whole Numbers it is important,

2. You have public ChangeColor method like this. Put this method any your object and add it to your slider's On Value Changed() method.

    public void ChangeColor() { PickColor ((int)bgColorSldr.value); background.color = color; }
