To create an innovative automotive dashboard, we evaluated different foreground/background colour combinations. Two achromatic (black/white and white/black) and two chromatic (amber/ green and green/amber) dashboards were tested. Twenty participants performed a primary task (tracking of a moving target) and a secondary (matching) task. If the primary task was correctly executed, the secondary-task target (a speed-limit sign) was displayed. Observers judged if the speed indicated on a simulated dashboard was higher or lower. Reaction times and errors were measured. Performance was better in terms of accuracy with a superiority of increment (white/ black) over same-contrast decrement (black/white) dashboards. Among decrements, the chromatic amber/green solution was better than the achromatic black/white. Among increments, the white/black solution was always the best.

Abstract
To create an innovative automotive dashboard, we evaluated different foreground/background colour combinations. Two achromatic (black/white and white/black) and two chromatic (amber/ green and green/amber) dashboards were tested. Twenty participants performed a primary task (tracking of a moving target) and a secondary (matching) task. If the primary task was correctly executed, the secondary-task target (a speed-limit sign) was displayed. Observers judged if the speed indicated on a simulated dashboard was higher or lower. Reaction times and errors were measured. Performance was better in terms of accuracy with a superiority of increment (white/ black) over same-contrast decrement (black/white) dashboards. Among decrements, the chromatic amber/green solution was better than the achromatic black/white. Among increments, the white/black solution was always the best.
