Here are the most recent additions to my MAC neutral eyeshadow collection: Brule, Soba and Retrospeck.
Brule is a creamy beige with a satin finish. This will make a good natural looking highlighter especially for those with yellow undertones.
Soba is a mid-tone yellow based brown that's perfect for the crease.
Retrospeck is a glittery light beige in a lustre finish. This is beautiful as a lid colour.
