Oops. Sorry. To use the type as a fixed color that command should have
been   ... using 1:2:3:(column(4+type)):(type)
where "(type)" in parentheses is evaluated once, giving a constant value, 
instead of "type" with no parentheses which is interpreted as a column
number containing the color value.

These are C-language formats.
So  sprintf("Type: %d",type)

See above.  
Or else use type as a parameter to a function that returns
a color value.
