OK.. I need the expertise that can only be found here...
I have a customer who wants some petit fours dipped in white candy melts. That I don't have a problem with. I usually use Wilton's white candy melts and she loves these. However, she wants them to resemble the scottish flag so she wants the candy melts colored royal blue 
with a white "x" on them. I've been stressing about how to do this. How should I color the candy melts this color blue? I usually use the recipe (I think I found it here) that calls for adding some heavy cream to the candy melts while they are melting. Can I add some of my paste color to this or will the paste color cause the candy melts to seize up? For the "x" I thought I would either paint on with melted white candy melts or try to paint on with luster dust. Will white luster dust show up really white? What should I mix it with? I'm really clueless here. They are due in 2 weeks and I only have a Joanns and Michaels close by to get supplies... that is unless someone in the Columbus, OH area knows of another supplier. 
TIA

You will need to use an oil-based food color or the candy will seize. I read on one post that there is something you can buy to add to the paste or gel food colors that will allow you to add it to chocolate without the chocolate seizing, but I can't remember what it is. (I think it's made by Americolor, though).
My Michael's had candy food coloring. It came in a box of 4 colors and I think they had primary colors or pastels. I'm not sure how much of a "royal" blue you could get from them, but maybe if you start with the blue candy melts and add more blue coloring to them, you could come up with the right shade.
I've heard that people add a little Crisco to they regular paste food coloring and that seems to keep the choclate from seizing, but I've never tried it & I would think it would change the consistency of the chocolate too. Maybe try it in a small batch and see what happens?
Good luck - the petit fours sound really cute!
Yes, they add paramount crystals to chocolate to help it stay fluid. I have use a small amount of crisco when I don't have the crystals. You could also use cocoa butter.
As for the luster dust. I've never been able to get white to show up. I would pipe it with white chocolate.
I have not had good luck adding heavy cream to the candy melts, it makes it unable to be used (very funky texture very similar to melted cheddar cheese).
However, I have seen the pre-colored melts by wilton on occassion in JoAnne's, you may be able to get your blue that way, and if it is too dark use the white to get the color you want.
As for the X, I would use royal icing, you can either pipe it directly onto the cakes, or make them ahead and let them dry and place them on the top.
when I made the candies for the baby shower cake in my photos, I originally wanted to make them blue. The lady at the cake and candy shop told me that you need to use either colors specifically for candies, or a powder food color. Check with your local cake and candy shop to see if they have the powder stuff. She told me that it does not change the flavor or consistency at all, and that she's used it for years with great success.
Good luck! They sound really neat!
The times I've added cream to candy melts, I've ended up with more of a ganache that's sticky to the touch, instead of the smooth, dry coating.
I would use the candy colorings to be on the safe side. Adding the shortening does thin the melts a little bit for smoother dipping.
I have the hardest time piping with warm chocolate or melts, I just don't have the control I'd like, so I've taken to using royal icing when I need precision. I think you could do them in white royal and then, after it hardens, maybe paint on a little white or pearl luster to give them some glamour!
My Michael's has several colors of melts, as does Hobby Lobby and AC Moore, if you have either of those stores.
There is a Cake and Cany Supply store really close to the Columbus Airport, it's off Johnstown Rd.
It's called happy Hostess and they have everything you would possibly need for this....they have the colors for chocolate and the ladies there are really really helpful!

i made a dark royal blue candy color a couple of years ago for my sisters baby shower (i don't have a pic though) what i did was buy the blue candy melts then i bought some candy color and added blue candy color to the already blue candy melts and it worked pretty good.

Thanks cakekrayzie... I think I'll try this. I've looked at the blue ones at Joanns and they are too light a blue so hopefully this will work.
Mandica... thanks for the info. I'll try to make it over there this weekend... you are so close to me! I'm right down the street in Orient. Love your pics! I especially like the OSU one 
and the Thomas one. My son wants a Thomas cake for his birthday in September. I may have to pick your brain on that one if you don't mind 
Thanks again!
