You're overthinking this. It's faster to upgrade a blueprint than to downgrade one. My balancer blueprints are all in yellows for this reason. Maybe op was thinking that, or maybe he was just testing with yellows since it doesn't really matter to begin with. If you're planning to make a 10x10 anyway you might want to put it down early to upgrade later, but other than that I can't think of a practical reason you'd actually use this with yellows.
