Never understood downvotes on questions or on economics. The cost of something affects how well it will scale. This is like downvoting a question about performance specs. Cost is a performance spec that determines scaling.
If you were planning on building these for something where the cost of the parachute would actually matter, and need to do so at scale, perhaps you'd switch to a single-color parachute (with simple orientation/tracking markings). This discussion isn't really interesting at all.
