    In UI image object, when source image is None. It renders a white sprite.

    UI Image multiply Sprite=None with Color(defaults to White with full opacity) and show White Image even when sprite is not assigned. This is not the same behaviour as in 2d Sprites.

    Is it the desired behaviour in 4.6 or a bug?
    If it is desired behaviour, what's the best way to suppress it?

    image.enabled = false
    image.gameObject.SetActive(false)

    Its the same behavior like the default (not GUI) shader.
    If you have no image supplied the material will still use the Color.
    I would say its intended.
    You could set the color to transparent and if you assign the sprite you can set the color back to white.

    This is a great way to lose track of the object and never to be able to set a sprite on it again.

    Thanks, this is the best though weird solution. Transparent being Color.clear (which I just found out).
