Unfortunately, Red is a primary color, and thus you cannot mix any colors to make it. You will have to buy red coloring in order to get it. You also cannot make yellow, or blue as they are primary colors.
Previous answer: white and black
My answer: Since white and black food colouring may be difficult to come by, you should be able to achieve success using any colours EXACTLY OPPOSITE each other on the colour wheel. Red and green should work. The trick is to get the right quantities.
Well, no two colors make black but there is three. try an equal amount of red yellow and blue food coloring.
Yellow is a primary color. No colors can mix to make it. You will have to get yellow food coloring.
You can't make red food coloring. It is a primary color, and must be bought.

No colors can make red. Red is a primary color, and can be mixed with other primary colors to make different colors.

The only way to make a truly black frosting is to use black paste food coloring. It is not possible to get true black by mixing other colors, and liquid food coloring is not dense enough to produce anything close to black.
Im going to say yellow and red.
You will need powdered food coloring and jelly (If you want you can use sweet jelly). Mix the jelly to a smooth paste and add the powder. :)
You can not make candles with food coloring, they are made out of WAX.
Fuisha is a pink, the closest colour to it is red. If you add water to it will turn to pink.
The only way you can make it gray with food coloring is if the substances you are making the volcano out of is white. You will have to add black food coloring drop by drop until you have the color gray you want. If you can't find black food coloring, mix every color you have together then drip it in. All of the colors mixed together will make black.
