Color Overlay Graphic Effect Needs Improvement

Ever since it was implemented, applying the colorOverlay graphic effect results in visible artifacts present at the edges of rounded and angled controls. The issue appears to be the combination of the overlaid color with the antialiasing of the underlying target object, and is most noticeable when the color opacity is 100% (255).

A demonstration stack is attached. The current results are unprofessional and should be improved.

Hi Scott,

I noticed a visible improvement if we change the Blend Mode
(inside the Color Overlay panel) from Normal to Multiply.
Could you see this change?

The multiply blendMode works when the target object is white or a light color, but is not a long term solution. Change the backColor of the target object to black and you'll see why.

The colorOverlay effect is based on the Photoshop effect of the same name. Attached is a comparison of the two results.

It's true if you jump through some hoops, you can sometime find a tolerable workaround, but when delivering solutions to clients, you can't expect them to know how to solve this type of issue. It should just work.

Scott, I just searched the bug DB for this but came up empty. Did you submit it? If not, please do. Thanks.
