Not really. I looked into it a while back.
Most paint is designed to be opaque. The inks on a marquee is meant to diffuse the light.
I experimented a little bit with single sheet of paper to diffuse the light even further, that showed some promise. Especially for "dots" of light.
I was at an art gallery and noticed how rich some of the water color paintings are. I realized, that with a sheet of paper, one could probably use water colors on the paper and feather the colors. I'm not very artistic though and I really haven't gotten around to experimenting.
I don't know if it's still sold, but Testers used to sell translucent colors, both in the small 1/2(?) oz bottle and in the spray can. I bought five or six of these just before I quit modeling. I imagine with a layer of Triple Thick and careful mixing and application of the translucent paints, one could match and blend the colors on the marquee. But that's a lot more tedious than the paper trick above and a lot less room for error.
Last I checked, I read of one report of someone successfully matching the paints on the marquee (for a pin) but they were pin holes and I don't believe there was a back light. I could be wrong about that though. I find something new everytime I look at someones projects.
