The Extravehicular Mobility Unit is the white hard-shell suit that keeps a human alive outside the spacecraft. Its Thermal Micrometeoroid Garment — layered Ortho-Fabric of Gore-Tex, Kevlar and Nomex — is engineered white to reflect solar heat, quilted into channels and cut by deep-space shadow at every seam.

This system reads that surface literally: a cool grey-white ground, never cream or warm paper, marked only by NASA's identification-stripe blue and commander worm red. Wide aerospace display type, connector-ring geometry and mission-patch roundels carry the engineered, mission-brief discipline of human spaceflight.
