I've been using either my Urban Decay Naked palette, theBalm Shady Lady vol. 2, or Cast Your Shadow face palette pretty much every day the past couple of weeks. The shadows are all just such good quality, I can't help myself! With this frequent usage I've noticed a few similarities in shades. Last night, I got to swatching them side-by-side to see if I could find any dupes. I didn't find any
dupes per say, but the few you'll see below definitely have similar qualities!
Hopefully this will be helpful if you have one or the other, or especially if you can't find the Muppets Cast Your Shadow palette (or the Bold and the Beautiful). And if you know of any other dupes/shades that come close, feel free to post them in the comments!
Round One:
L-R: Celebrational, Insane Jane; Woman, Woman, Makeout Mary; Caught In The Act Courtney, Mahna Mahna, Hustle
Taupes: Celebrational (Cast Your Shadow) vs. Insane Jane (Shady Lady Vol. 2)
In terms of pigmentation, Insane Jane wins overall. Celebrational is still a gorgeous taupe, but Insane Jane packs more punch and has a bit more dimension with the shimmer. The colors themselves are in the same family, however.
Grassy greens: Woman, Woman (Cast Your Shadow) vs. Makeout Mary (Shady Lady)
Like the taupes above, Makeout Mary from the Shady Lady palette really shines. If this speaks anything for the other volumes of theBalm Shady Lady palettes, I really need to try more! Such great quality shadows. Anyway, both greens are yellow-toned with gold shimmer, but Makeout Mary is a bit more pigmented and warm-toned.
Chocolate browns: Caught In The Act Courtney (Shady Lady) vs. Mahna Mahna (Cast Your Shadow) vs. Hustle (Urban Decay Naked)
These are each a very different shade of dark brown, but I thought I'd include the comparison anyway. Both theBalm shadows (center and left) have glitter, as opposed to UD Hustle which has subtle shimmer. They all lean on the reddish side of brown with varying pigmentation and finish; Mahna Mahna appears almost burgundy in swatches.
Round Two:
L-R: Tres Moi, Toasted; Wocka, Wocka, Darkhorse, Celebrational; Muppetational, Gunmetal
Coppers: Tres Moi (Cast Your Shadow) vs. Toasted (Urban Decay Naked)
TheBalm's Tres Moi is a gorgeous copper brown if you like these types of colors. It's rich without being over the top and frosted. UD Toasted is of the same family except it has more of a metallic finish and is more cool-toned.
Olives: Wocka, Wocka (Cast Your Shadow) vs. Darkhorse (Urban Decay Naked) vs. Celebrational (Cast Your Shadow)
Alrighty, Celebrational isn't an olive shade whatsoever but after swatching the first two side-by-side, I realized they leaned more brown than green. Wocka, Wocka takes a couple of swipes to get solid pigmentation and has more green than UD Darkhorse, which looks greener in the pan than when swatched. These definitely aren't similar to one another, but I thought I'd show the comparison nonetheless!
Greys: Muppetational (Cast Your Shadow) vs. Gunmetal (Urban Decay Naked)
Again, not similar enough to compare, but in the pan they look closer in color! Muppetational is definitely more silver and lighter than Gunmetal, which is a darker grey with chunkier silver glitter.
Round Three:

L-R: Meep, Meep, Mischievous Marissa; Lab Coat, Tempting Tara; Hii-Yaaa!, Virgin; Swedish Pancakes, Sin
Rust oranges: Meep, Meep (Cast Your Shadow) vs. Mischievous Marissa (Shady Lady Vol. 2)
Meep, Meep is definitely darker and has more brown than Mischievous Marissa, which has more yellow. They both have a similar metallic finish and great pigmentation.
Whites: Lab Coat (Cast Your Shadow) vs. Tempting Tara (Shady Lady Vol. 2)
These are very similar in color, but Lab Coat has a smoother/softer formula overall. Tempting Tara from the Shady Lady palette applies a little unevenly in comparison and has silver shimmer.
Light beiges: Hii-Yaaa! (Cast Your Shadow) vs. Virgin (Urban Decay Naked)
At first I thought Hi-Yaaa! would be more comparable to UD Sin, but I was wrong! It applies a lot brighter and lighter on the skin than it looks in the pan. It's more metallic than Virgin and packs a bit more beige color.
Champagnes: Swedish Pancakes (Cast Your Shadow) vs. Sin (Urban Decay Naked)
Swedish Pancakes definitely leans more pink than Sin, which is more of your true champagne color (more beige and less pink). Sin also has more of a metallic finish as opposed to straight-up shimmer.
I hope this helps you decide if you need one of these palettes, or if you have anything similar in your current collection!
Have a great Monday night everyone. xoxo
