I need to make Magenta orchids :/

I’m not sure what brand of food color you use but I have this chart which might be of help. http://www.sugarcraft.com/catalog/coloring/colormixingchart.htm
I would try the combination they have as raspberry and see how close that gets you. Hope this helps.

I have used americolor fuchsia to get that color, first I tried mixing it but never succeeded… According to the charts it should be purple and red mixed but it never looked good so I just bought it. You could even try Americolor Electric Purple but that one is a bit more dark than fuchsia. Hope this helps :)

ps. I took a photo of both of them, maybe this will help you to see how they look before you decide if they are the right ones :)

I have had good results with rose rosado of wilton. But you can also make them white and dust them with a nice bright pink dusting powder

Thank you so much everyone I really appreciate it xx

try wilton burgandy in lesser concentration>?

Many thanks everyone, as you may have seen I have now done my orchids and they turned out pretty good. I used a combination of powders in the end as the americolour arrived after I had made the flowers, but this brand have lovely bright strong colours and I shall look forward to using it. x

they turned out wonderful Elizabeth!
