Having tested my Cashmere foundation samples in Light Medium Golden and Light Medium Warm over a period of 3 weeks, consistent wear, I have decided to ditch Everyday Minerals for this.
First of all, colour match wise, both Warm and Golden are perfect for my light-medium Asian skintone (MAC NC25-30/C3, Alima W3, EDM Golden Light/Olive Golden Medium, Carmindy Your Skin Creamy Beige, RMK 103). I would say they are suitable for NC25-30. I am more of a 30 right now, and Light Medium is a smidge lighter. However, as I'm currently living in Hot & Humid Land, I'm going a little lighter to allow for oxidisation. Warm is not as pink/peach as Alima's Warm, and Golden is not that pure yellow shade that you see in Alima's Golden. I'd say both Lumiere's Golden and Warms are in between Alima's Warm and Golden, with maybe a touch more green in Golden. Both Lumiere's Golden and Warm are very yellow-based, so be aware if you are more neutral.
Texture-wise, Cashmere is a very, very fine powder that goes on very smoothly and doesn't appear to cake significantly after a few hours of wear. I have combination skin with some dehydration and surface oiliness in my T-zone. I'm not sure this cuts shine (nor do I want to look completely matte). It's not shimmery like EDM semi-matte, but also not as matte as Alima, I feel. (Alima, while a nice, resilient formula with good coverage, has the tendency to make me look 10 years older!)
Most importantly, this feels weightless on, and coverage is sheer but as with all minerals, very buildable. A 2nd or 3rd layer doesn't look cakey on me - however on EDM, I have to be careful because extra layers cake/look blotchy.
I ended up purchasing Light Medium Warm, as it was a better match for me. There's not too much difference between Warm and Golden, I feel.
