Rescue Beauty Lounge Be Humble is a neutral-toned, light taupe with a pearl finish. It is a limited edition nail lacquer that retails for $20.00 and contains 0.5 oz.
Rescue Beauty Lounge Be Humble Nail Lacquer ($20.00 for 0.50 fl. oz.) is described as a "taupe ... [with] pink, blue, and lavender shimmers." It's a warm, muted, light-medium mauve with fine pink and lavender pearl (I couldn't really pull out the blue). It applied well and was opaque in two coats. The formula is on the thicker side but the consistency didn't affect the performance or application. Cult Nails Let's Get Dirty is slightly pinker and warmer, but it is similar and the only shade I could think of that was similar (it also has a wax finish, so you'll need a top coat to replicate the shine of Be Humble).
