Ardency Inn Americana Custom Coverage Concentrate Swatch
I know this isn't the best swatch and I'll try to get some better shots (my phone is really old), but for what it's worth, this is a swatch I took comparing the Ardency Inn Light Golden (middle swatch) to Becca Radiant Skin Satin Finish Foundations samples - Shell is on the left and Sand is on the right. The Ardency Inn is mixed with Hourglass Veil Mineral Primer - about a half and half ratio.
I'll try this weekend to borrow my friend and her phone to take some better swatches. These were under bright, kitchen lighting. I think you can see that the Light Golden does lean towards yellow and while it's light, it isn't as light as the Shell or Sand.
I've been wearing it for about 3 weeks now and still really loving it! I found I can mix a "batch" in a jar and use it all week which is very convenient.
