I am going to be making a motorcycle cake this weekend and the gas tank of the bike is an electric blue color (I think).

My question how would I achieve this colour? Use blue fondant with luster dust on top maybe or white fondant painted with blue luster dust or maybe another suggestion.

Any help would be appreciated. Thank You.

They have a blue luster dust that would work really well.Im making one myself for a grooms cake this weekend but its red! Good luck on yours!

I would paint with blue luster dust ON blue fondant, when you apply luster dust on white you can notice the brush strokes and on any colored fondant underneath "matching" luster dust, the color sets better and pops out =)

can I ask do you mix the lustre dust with anything???

vodka.. extracts..
i prefer passionfruit rum )

I am thinking I really need to stock pile vodka its a really cake decorating must isnt it!!

Giannina - Thanks for the info. I'm going to buy some blue fondant (Duff's) tonight at Michaels along with some blue luster dust and maybe blue disco dust if they have it. Is that edible?

I have heard bad things about duff's fondant, just as an FYI. he does have some interesting coloured food colours though.

ABout the "disco dust" being edible, CK states:

American Blue Disco Dust
Made in the United States. They are classified as "non-toxic for decoration only". The weight is listed as an approximation per the packaging label.

OK, no disco dust for me then.

Erin - I have actually tried Duff's fondant in black and really liked it. It tasted great and was really pliable. i think it would not be good for little items or molding but for covering a cake it is great.
