When I tint translucent, it gets a lot darker in color after baking. Anyone know what to do to keep it the pretty light color it started with?

 people say if you bury it in cornstarch that helps with this issue. I never tried it. I also think you'd need to add extra baking time if you did that.

 I know Premo has a version of translucent that contains some bleach -- "frost" I think?  Does this hold the light color better? Anyone know?

The other thing I might try is adding white to the tint until it's getting close to the shade you want and THEN mix that with translucent.  But I haven't really tried that.  I think, though, what's happening is that the translucent gets more clear as it bakes, so it doesn't dilute the tint color as much, so adding some white would lighten it, but would also make it less, well, translucent.

I used Frost and started with the color I wanted. After it turned too dark I made it over again adding more white to the tinted Frost. I was making a light switch cover for my new great-grandson's room. I haven't seen the color so I'm going to let his mom decide which one she wants. I put a moon and stars on it in glow-in-the-dark polymer clay.

 Sounds cool anyway!

I would think that adding white (or any other color via clay) to translucent is just going to reduce its translucence. When I color trans, I use alcohol ink. Sometimes it's a crapshoot and the colors darken, albeit often for the better. What about using less colorant?

Different brands of translucent are more or less translucent than others.  Premo, for example, tends to bake to a grayish color unless it's very, very thin.  

You might want to try making your object out of a very light hue to put behind the translucent, and keeping the tinted translucent layer almost paper thin.  I would do a test piece first to see if that will preserve the color you want.
