What we can see of their one dimension
The observer can not differentiate one object for another. The use of colour introduces separation but does not amount to a new combination created.
Only seeing line colour or the combined of two lines provides no shape for this movement, which is required. Lines surrounding images only provide eight of the apparent 360 possible views from a set distance.
A grid to understand the shape of the thing, right left back or forward counting, never knowing if you ever get around.
