I have an array(ColorsArray) that contains vectors with elements that are colors of the type RGB{Float64}. I arranged these vectors into a matrix by doing: reduce(hcat,ColorsArray).  
I wanna take the transpose of this matrix but I got the error:  
MethodError: no method matching transpose(::ColorTypes.RGB{Float64})  
How can I take the transpose of this matrix in julia?
