Exposing Nail Polish True Colors

Ever buy a nail polish only to find out when you get home that it looks completely different from what it looks like in the bottle?
I have recently started adding new manicure services, adding Shellac and OPI Gel to my list; Shellac is kind of cool , while it looks like real polish it lasts 1-2 weeks and is non harmful to your nail-you dont need to buffer the nail to put it on, or scrape the nail to remove.
Anyways most of the Shellac colors I got were adorable. But I like more light pink colors, colors like "Mod about you" from OPI regular polish range ...
trying to find a shellac and OPI in a similar tone and opaqueness has been really impossible.
I am going to start posting my pics of what my nails look like after I apply colors so you can see what it look like on a nail.

Here is OPI Gel Princesses Rule with Shellac Romantique:
