Can anyone tell me how I can get dye gum paste a maroon red?
thats a hard color to achieve depending on what you are making i would either add alittle brown to red. Or what i prefer to do (when making flowers that can handle a variation) I would start with red paste, then brush dry powdered color over it in a brown and finish with a red layer. It is something you will have to play with to get the color right for you. But i find when looking to make different colors that layering the colors one on top of the other works very well.
Also, you may want to check out crystal colors (www.sugarpaste.com) they have a wide assortment of high quality colors to choose from.
