    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
