Labeling overwrites "Red" values of RGB point cloud

[jobberz77]

I have been labeling RGB point clouds with this tool and so far it has worked pretty great! I have encountered a problem however. When I try to label an RGB point cloud, the "red" column(4th column, just after X Y and Z) gets overwritten with the label value. This throws off my point cloud colors resulting in very bright blue and greenish point clouds.

Perhaps I can bypass this problem by inserting an empty "label" column as fourth column before labeling. It would be nice if the tool would add the label value to a new column instead of to the fourth column by default.
