The RGB model, which combines red (analytical performance), green (environmental impact), and blue (practicality), is at the heart of the concept of white analytical chemistry (WAC). While this approach has helped broaden the field’s focus and offered a more balanced evaluation system, analytical science continues to move forward, and with it come new priorities that extend beyond what the RGB framework can fully reflect. This final article of this week's series on WAC curated by Adrián Fuente-Ballesteros of the University of Valladolid (Spain) presents new tools intended to fill that gap.
