Aluminum (10M) is a bright, light silver with neutral-to-cool undertones and a sparkling, metallic finish. It had good pigmentation in a single layer with a slightly dense consistency that felt a touch thicker but wasn't overly creamy. I found that some of the sparkle diffused too readily away from the base color, which sometimes led to light fallout. The finish was very reflective and seemed to reflect the warmer tones of the shades I placed around it to the point where it didn't look that silvery! It wore well for eight and a half hours before fading but had a touch of fallout over time.
This shade felt largely unchanged from my original in color, but the finish was more sparkly in the current iteration and felt a bit drier as a result.
