    Hi!

    Code (CSharp):
    1. Color Sandra = IMG.GetComponent<Image>().color;
    2. Sandra.a = 0x00;
    3. IMG.GetComponent<Image>().color = Sandra;
    Its ok! Alpha = 0

    Code (CSharp):
    1. Color Sandra = IMG.GetComponent<Image>().color;
    2. Sandra.a = 0xC7;
    3. IMG.GetComponent<Image>().color = Sandra;
    Doesnt work, alpha = 255. I need 200. How to make alpha 200?

    In code, color values use the range 0-1 instead of 0-255. You can find your color values by dividing the color value you want by the max value (255).

    200 / 255 = 0.784

    So this is the code you want: 
    Sandra.a = 0.784f;
    or 
    Sandra.a = 200f / 255f;
