Heehee, what Dawn, you don't like the Wilton colours, really? Haha!
Ok, enough fun, I have to say that I agree on this particular colour, there is no way in heaven to get a true brown using the Wilton brown unless you do add cocoa or melted and chocolate, it just doesn't do it on its own! Regardless of how much of the Wilton brown you use, it just won't happen. Now I do find that you can get any other colour to work with the Wilton colours, although, for the darker colours you do use a lot. The advantage with Wilton colours, is that you don't get as much effect from the liquid as they are way less liquid than most other brands. So when you are mixing up red fondant for example, you use a heck of a lot of colour, but less icing sugar to make up for it being sticky. Whereas the others have a lot more liquid and therefore colour faster.
But the brown, well it is a big problem!
