Most all the bc/cc oranges and coppers (and many other colors) are a very translucent color, the shade of the sealer is critical to get the shade of the paint right! Too really get orange to "pop", using the right base under the orange will really change the characteristics of any color with pearls in it!!!! Might want to consider getting a pint of the color you're considering mixed up, then try it over a few different shades of sealer and different base colors. You can create lots of different effects with translucent colors, just try some different things til you come up with a combination you like!
