Make overlapping shapes appear opaque while still retaining multiply transparency effect?

Question

I created a design for a logomark that consists of a series of overlapping U shapes with a Multiply transparency applied.

When placed over a dark field, depending on the hue, part of the design disappears or doesn't provide enough contrast.

Is there any way to retain the original design with the multiply effect, but convert it to normal opaque transparency?

I thought it might work by pasting an opaque white duplicate behind the original design, but the results are what you see in the 3rd image.

Is this just the optical result of using these 2 hues of blue and green against a darker hue?

Since it's a logomark, I need it to ideally be able to work against a variety of different backgrounds.

Hi @GPDX,

So that you don't have transparency issues in the future (especially when printing), I would recommend using solid colours for a finished logo. I understand you'd like to keep the transparent effect; however, your opaque white object / 3rd image that you posted, is correct.

Here's how to remove your transparency but keep the object's inner appearance:

Duplicate the logo (always, so you have a backup). Draw a box overtop of your duplicated logo - fully covering your logo. Select both the box and new logo at once, then right-click and make a clipping mask. Next choose Object > Flatten transparency. Adjust the settings as needed, but make sure "preserve alpha transparency" is OFF. You'll be able to delete the box around it, and all your shapes should now become separate, solid coloured obejcts.

As far as using transparency effects, you can try using "lighten" and "screen," and some of the other options to see what looks best on dark backgrounds.
