Default Injector Swap?

Hi all. Injectors aren't my strongest point of knowledge so best I ask I reckon. I have a 2wd sapphire with L6, and for this conversation say about 300bhp. Currently it has the yellows fitted, but I have a set of dark blues kicking around....
I'm told they are std 4x4 ones, have a flow rate that is only slightly better than yellows, but a better spray pattern? Is this true?
Assuming that is correct, can I just swap them over to my setup? Aesthetically they would look better in my bay and maybe the slight increase will help til I can afford greens and L8 which I plan to do in the future.
Any thoughts as to whether this is viable WITHOUT having to buy a new chip/remap?

If they have a higher flow rate they will obviously over fuel, but won't be as dangerous as running lean, the LIGHT blues are good for 350-390, what is the part number of the dark blues, I'll look it up for you.
Why not just keep things as they are all nice and correct, till you have everything ready then swap things over ?
Just because they may flow more fuel does NOT guarantee more power, it will still lose power over a better afr if too rich, and belch black soot!!
I can't see there being a difference in spray pattern, between the two, unless one is fitted to some oddball engine as std.

You won't be able to just swap them, as your software isn't mapped for them, light blues IIRC are 4x4, the only reason for wanting to change injectors is if your current ones are in capable of fuelling for the engines needs although arguably a better spray pattern may count to a small degree, if this were the case I would be going straight for Siemens 55LB.

Overfuelling is as bad as underfuelling!
