error with changing color of marker using scatter3

I want to create a 3D scatter plot using different colors for each marker, which is information contained in rgb. I keep getting errors, and I can't figure out what is going on!

I checked that the dimensions of Table are 50x4 and that rgb is 50x3 with numbers only 0-1. I tried a test using this "colorvector" and that also did not work, so I don't think it is something to do with the file.

Table = readtable(DataFilePath);

Map = [Table.Var2/360, Table.Var3/100, Table.Var4/100];

rgb = hsv2rgb(Map);

%Colorvector= repmat([0,1,1],height(Table),1);

scatter3(Table,"Var2", "Var3", "Var4", 15, rgb);

It generates the scatter of just Table and the variables with no other modifications , but I can't get any color modifications to work. The error message is "Error using scatter3 (line 57) Invalid parameter/value pair arguments. Error in ScatterplotAttempt1 (line 16) , scatter3(Table,"Var2", "Var3", "Var4",15, rgb );"

See Plot Table Data with Custom Marker Sizes and Colors for a more extensive discussion.

Table = table(rand(10,1),rand(10,1),rand(10,1),rand(10,1))

Table = 10×4 table
     Var1        Var2        Var3        Var4

figure
hs3 = scatter3(Table, 'Var2', 'Var3', 'Var4','filled', 'ColorVariable','Var4');
