Celeste McCollough Howard (September 12, 1926 – January 30, 2023) was an American psychologist who conducted research in human visual perception.
In 1962–63 during her first sabbatical leave, she conducted research in Canada into the perceptual effects of wearing spectacles tinted with two colours (McCollough, 1965b).
Her work on the dim light available from early color displays led her to participate in the Commission International de l'Eclairage (CIE) division on mesopic photometry (e.g., Howard, 1997).
After 1995, she joined the Air Force laboratory's Night Vision Training Research Program under contracts held by private corporations.
This research included studies of early mesopic adaptation to luminance decrements encountered in the cockpit while wearing night vision goggles (Howard, Tregear, & Werner, 2000).
