2. Enter Play mode
3. Click on the numbered buttons
4. Observe the bottom row of pictures (upper row is correct result)

Expected: Image alpha is changed via script
Actual: alpha is not changed if Image type is set to Simple

I have this issue on 2019.2.19f. Same as HEXADIMENSIONALERALP said below, the color wheel shows correctly but image is white.

I'm using 2019.3.0f3 and it still happens on image type sliced or simple, but only sometimes. When opening the color-wheel it shows the pointer on the position of the rgba I assigned via script, but does not apply the change to the image.

I upgraded to Unity 2.1.0f1 and I'm continuing to have the same issue (no change of source image or material, just setting color.

Version 2019.1.6f1 still has this problem, how many unity installs do we have to have on our machine in order for one feature to work?

2018.4 LTS version should also have this fix, right?

This fix will probably also be in 2019.1.5f1 and 2019.2.0b4

When finally backported to 2019.1 & 2, will it be feedbacked on this issue tracker too ? (since it's already occupied by the mention 'fixed in 2019.3').

Well, Unity 2019.1.4 is released, and this is still NOT fixed. Disappointed.

I feel changing alpha and sprites in an animation is a pretty basic thing that happens way too often in even the smallest project.

This should be backported to 2019.1 and 2019.2 instantly. It's currently blocking updating to newer versions for way too many projects of devs I know.

Please, help us Unity. Thanks!
