[Bug] Image color transparency not working in code

Unity Engine
1

Hi.
I started using unity 4.6 new UI.
I’ve a code where I change a UI.Image transparency with this line:
image.color = new Color(255,255,255,100);
But this doesn’t work.

After a few test I found that changing the color do work except for the alpha value.
If alpha = 0 then the image is invisible but anything higher than 0 make the image fully opaque.

Changing the alpha value manually in the inspector do make the image transparent.

The Color values are floats between 0 and 1.

Thanks. I thought the values were between 0 to 255

You can use the more familiar RGB 255 syntax if you use the Color32 type instead of Color type. Unity will convert it for you into the Color type. Would be nice if they added a hex parameter constructor option!
