L.A. Girl PRO.color Foundation Mixing Pigment, Blue GLM714

Sure! It's just the LA Girl Foundation Adjusters, they're pretty inexpensive on Amazon, but for some reason the red/orange one is separate. You are probably mainly going to be using the blue one, which you can find here. The red/orange one, if you need it, is here. The temptu adjusters are quite a bit more pricey, but i do use the lavender and black quite often, since things that are way too pure yellow will often need some red added, and if you need to darken a shade a bit as well as cool it down, the black is actually quite useful. You can find them here, or the full kit here. It's worth noting that these aren't the only ones that exist, or that are good formulas, but they're just the ones I find the most useful and the LA Girl ones are honestly the best bang for your buck, they're dirt cheap and work fantastic every time. I hope this helps!

Oh, I’m uk based too! In that case, here you go: https://www.amazon.co.uk/gp/aw/d/B07HPFVH1K?psc=1&ref=ppx_pop_mob_b_asin_title So, I’m using two finely milled eyeshadow monos from Laka as blushes in modernist (for a cool muted cool toned blush) and Earth (for a warmer but in no way orange blush). I also just got NARS Mad Love today - it’s mauve in the pan but pulls slightly warmer on me (I’m cool toned olive and turn almost everything orange!) but quite naturally and not orange. This is me wearing it. It also has a subtle shimmer so is much more skin textured than the other two which are flat matt.
