Need help fixing simple function

I have a function that simplifies coordinates and colors

The part that edits the coordinates is correct, but the colors is not

Here is the function

%function positionsnew = CubeLayout(RawCoords, Colors)

%Pre allocates newcoords
newcoords = zeros(9,1);

RawCoords = MrCoords; %JUST HAVE THIS AT THE MOMENT TO TEST 

%This determines the position of the coordinates
for k = 1: size(RawCoords,1)
    if RawCoords(k,1) == 1 && RawCoords(k,2) == 1
                newcoords(k,:) = 1;
            elseif RawCoords(k,1)== 1 && RawCoords(k,2)== 2
                newcoords(k,:) = 2;
            elseif RawCoords(k,1)== 1 && RawCoords(k,2)== 3
                newcoords(k,:) = 3;
            elseif RawCoords(k,1)== 2 && RawCoords(k,2)== 1
                newcoords(k,:) = 4;
            elseif RawCoords(k,1)== 2 && RawCoords(k,2)== 2
                newcoords(k,:) = 5;
            elseif RawCoords(k,1)== 2 && RawCoords(k,2)== 3
                newcoords(k,:) = 6;
            elseif RawCoords(k,1)== 3 && RawCoords(k,2)== 1
                newcoords(k,:) = 7;
            elseif RawCoords(k,1)== 3 && RawCoords(k,2)== 2
                newcoords(k,:) = 8;
            elseif RawCoords(k,1)== 3 && RawCoords(k,2)== 3
                newcoords(k,:) = 9;
    end
end


%Colors second part of function

Colors = MrC; %JUST HAVE THIS AT THE MOMENT TO TEST 

%reshapes position vector and combines newcoords with Color 
positions = ([1 2 3, 4 5 6, 7 8 9]);
positions = reshape(positions,3,3);
ColorLocation = [newcoords,Colors];

%sets the color vector in a new 3x3 matirx 
positionsnew = zeros(3,3);
for i = 1:9
    for j = 1:9
    if ColorLocation(i,1) == j %if colorlocations column 1 row 1 is equal to 1 then,
        positionsnew(positions == i) = ColorLocation(i,2);
    end
    end
end


%end

MrCoords is this

MrCoords =

     1     3
     1     2
     1     1
     2     2
     2     3
     2     1
     3     1
     3     3
     3     2
    

Again, that part of the code is fine, and does not need adjusting, it outputs newcoords, which is a 9x1 matrix

MrC is this

     MrC =

     4
     5
     5
     1
     2
     1
     5
     6
     6

This is what I need done

ColorLocation combines newcoords and colors, this outputs a 9x2 matrix, the left side being a position, and the right side being a color.

I need to put the respective color in the location of the positions matrix, which is a 3x3

for example, positionsnew is the color output of positions and color location

     positions =
     1     4     7
     2     5     8
     3     6     9
     
     ColorLocation =
     3     4
     2     5
     1     5
     5     1
     6     2
     4     1
     7     5
     9     6
     8     6
     
     positionsnew=
     5  1   5
     5  1   6  
     4  2   6

Please let me know if I can clear anything up,
