MAC Spring Bling is a moderately warm-toned, medium brown with a satin finish. It is a limited edition blush that retails for $35.50 and contains 0.35 oz.
MAC Spring Bling High-Light Powder ($30.00 for 0.31 oz.) is a muted, medium-dark, reddish-brown with faint golden pearl. The overspray was strong, but I tried to get as much off of the powder by taking a large powder brush, swirling and swirling, and then taking another brush to get the loosened powder into a trash can before actually swatching and applying. I even took the back of a brush and dug out a divot in my pan to see if there really were fine shimmers in it, and I still saw them--very subtly but there.
The powder ends up looking more like a more typical satin-finish bronzer, so it might be a very subtle highlighter on medium-tan and deeper skin tones but will add some warmth and/or color along with a subtle glow (so at least it's in "highlighter" territory!). It wasn't a "sheer" layer of color at all; try mostly opaque and buildable. The sheen it gave was incredibly subtle, and I think the natural finish of my skin (normal at the moment) was doing more lifting than the product itself. The texture, though, is the high point of the product: velvety, creamy, and smooth without being powdery--it's much richer in feel than most of MAC's powder-based products (which tend to be firmer/stiffer, not necessarily in a bad way!). It wore well for eight hours on me before fading noticeably.
