I'm about to go travelling, and I always choose a light shade to wear and take when I'm going away. I learned my lesson about trying to take a base coat and top coat as well or attempting to use one of those base-and-top-coat in one. Having used other Sally Hansen Complete Salon Manicure polishes before, I knew that I was a fan so I grabbed Royal Blush.
Royal Blush is a pinky-peach semi-sheer shade that isn't too milky (depending on your skin tone). With three coats this colour is almost opaque, but there is still some slight VNL. I actually don't mind a bit of sheerness, but I find that it's a very subjective preference so you probably won't be a fan if you crave a strong and opaque colour.
I love the colour though. Soft without being super girly or make me look pasty. Very appropriate for travel as chips were barely visible. I tested the claims of requiring no base and top coat. I found I got a couple of chips after about 5 days of wear. I removed the polish after 7 due to my bad habit of peeling nail polish off once it starts to chip. Not bad considering how I rushed to put it on.
As for application, I really like the brush. It's easy to control; however, I swear mine is cut asymmetrically - something is a little off about it. However, it has a nice width and stiffness that allows me to work easily with it. Although it may have been the cut of my particular brush (I plan on re-cutting it I think), I did find that it didn't quite apply too evenly, but I find that this is usually not a big deal when you are used to applying 2-3 coats anyways.
All around a good natural/neutral polish to have on hand. I recommend having one that is marketed as "completed" even if it is just that peace of mind it gives when you don't have the time to or want to do a complete manicure. I would say that this colour is not necessarily essentially. There are other great natural colours in the line that would do the trick!
