Burberry Beauty’s Slate Blue No. 15 Sheer Eyeshadow Eye Enhancer ($29), is a sheer medium blue that plays well with the neutrals in the line. A reflection of the blues that appear in Burberry’s fashion line, this color applies more sheerly than it looks in the pan.
Although this looks like it would apply almost as a dark near-navy, Slate Blue applies as a shimmery, soft medium blue. Here is a comparison with Burberry’s Pearl Blue:
Slate Blue looks quite restrained, particularly when compared to a very deep navy like MAC’s Wait Until Dark (far right). This picture also compares Chanel’s Bois Bleu, which is similar in tone but adds more green, and Shu Uemura ME Blue 650, which is similar but has a more pronounced shimmer:
Overall, Slate Blue is the best choice to add a touch of subtle blue. If you are looking for a deeper blue in Burberry’s line, Midnight Blue would be the perfect choice.
