Ready To Roll Icing

[Chasingcars]

Hi!
I am making this cake next week for my daughters birthday...

http://www.lakeland.co.uk/info/owl-cake?intcmp=INTSRCH:owlcake

It suggests using ready to roll white icing and then brown food colouring but for the colours like blue and green, buy them as ready made colours...does anyone know why this is? Can you not get ready to roll brown...my thoughts are if you can surely it would be easier to do this as sometimes mixing a colour you don't always get even colouring? Or is there a more technical reason for this suggestion?

Thanks!

although it doesn't say so, the pictures show at least two different shades of brown, on the owl and the branches are not the same colour as the main bird either. maybe they say colour it so you can get the shading?

Hi woolfgang, yes good point. I have bought white with colour ready to add.
Do you know that when you roll the icing, you use icing sugar to stop it sticking but how do you get rid of any residue as its hard to wipe off without it snagging icing or leaving fingerprints!?
