One of my audiologists gave me a brochure about the brand that I'm buying, she never said anything about color, and none of my other audiologists made comments on color, they focused on what was most important for them and for me, of course.
While I was working on how to raise enough money for this expense, I also reviewed the pile of information on hearing aids that suddenly appeared in my life. Here Doc Jake at #18 and Psocoptera at # 19 said what I found out:
"... and whatever factory color you pick the cost is the same.
"... The price of making different colours is negligible compared to the price of hearing aids.
Oh! well, no matter the color the price is the same, here is when it came to my mind what you said.

I think you should go for either of those colors. You are the one wearing the HAs, and yes, you may as well have a little bit of fun with them.
