TEMPTU S/B Silicone-Based Shade Adjuster: Long-Lasting, Highly-Pigmented Formula For Customizing S/B Foundation Shades, Available in 7 Primary Colors

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!
