Why are the impellers blue?

I'm looking at the 6095's. Is there a reason why the impellers are blue, not black? It seems blue makes the pump stand out, which is the opposite of what I'd want for tank equipment.

Our logo and company colors have always been blue and it was an accent that they decided to add in 2010, prior to that Nano Stream propellers were white and Stream propellers were black. I think part of the reason is the plastic type, the old black ones were RC boat props and had carbon fibers inside, this made them black, the new ones are a more impact resilient polyethylene family plastic we mold ourselves and it is naturally white, I think it is difficult to make it a dark color. In general it is barely noticeable as the pump itself is black and the propeller is not very visible when the pump is installed and operating.
