The Wilton formulas shown here are made by mixing two pre-made Wilton icing gels.
The colors used are Golden Yellow, Lemon, Copper, Skintone, Pink, Rose, Red, No Taste Red, Burgundy, Brown, Kelly, Teal, Sky, Royal, Blue, Violet and Purple.
Colors used with abbreviations:
Golden Yellow is a bit more orange than Lemon.
Skintone is possibly a lighter version of Copper. Copper contains a bit of blue but mostly yellow and red.
Pink is just red food coloring. Rose is red and green ( a blend of yellow and blue food color). Both are from the Disney Hannah Montana Wilton icing gel set. The product numbers for these shades are on the linked page.
No Taste Red is red40, so it will not break. Red has some red3 because it will halo when mixed with blue. Find out more about working with red food color here.
Burgundy will crock if you use too much.
Kelly is a very strong color and will overwhelm the yellows and pinks.
Sky is pure blue, while Royal is blue and red. To learn more about using blue food color, go here.
Violet loses some of it's redness if you add vinegar too fast or add too much.
Purple comes in the Disney Hannah Montana Wilton icing gel set.
