Before you say "but the NARS is a regular foundation" - yes, I know. I'm including it simply as a reference for the color, since many ladies in the US are very familiar with NARS and not as familiar with Illamasqua.
This is not a review of the UD Naked Skin, because you've all read reviews already. I love the idea of all the bb and similar creams, and really like the texture and wear of the product.
Here's a little blob of each. I simply put a tiny squirt of UD Naked and Illamasqua SB on my arm, then used a cotton swab to dab on some NARS.
This is outside, no flash. It was overcast and raining on & off through the day, but we had about 30 minutes of sunshine so I rushed to do the swatches. Of course the sun kept hiding behind clouds, so sorry these pics aren't the brightest.

I realized I didn't have enough NARS to do a similar sized swatch, so I added another dab. Then I simply used my fingertip to rub the product down my arm, without blending it in. These next two photos are both outside, no flash.
I blended the foundation gently, again with fingertips. These pics are outside, no flash.

My initial thought on the UD .05 was that I was surprised they listed it as a "cool" shade. Compared to the Skin Base, it's not only darker, but more peachy. However, when I look at it next to the NARS, I can see the pinkishness of it. The phrase "shell pink" comes to mind.
I can use a touch of the UD .05 mixed with the SB and dab it on my cheeks to help minimize redness. I prefer doing this over using "green" color correctors, but I have to use it on just the affected areas. I can't use it on its own or mixed with the SB on my entire face, it's just too dark and too peachy beige on me. Maybe UD will make a shade to match me someday!
I hope you've found the swatches helpful, and thanks for looking.
