Question: Colored 3D Histogramm

Hi experts, I created a 3D histogram with(plots); with(LinearAlgebra); A := [[2],[3],[3],[4]]; matrixplot(A, heights = histogram, labels = [c1, c2, ExpectedProfit], tickmarks = [spacing(2), [seq(i, i = 0 .. 8, 3)], default], axes = normal) Now I want to assign a colour to each column. When the value is 2 of the Matrix it should be red for example, when it is 3 for example yellow and so on. Later Later I want to expand it to a Matrix with B[n,m]n=10 values... Thanks alot in advance for your help!
