— Many applications, such as AmbiLight TV and atmosphere creation with dynamic light, generate colored light that changes gradually from one color to another. However, there is not much scientific knowledge on how to create suitable color transitions. This study investigates what is perceptually the most optimal way to create a temporal color transition between two colors. The first experiment measured the ability to distinguish between two temporal color transitions. The reference transition was a linear interpolation between two colors in CIELab, the test transitions were arcs defined in different planes going through the linear transition. Discrimination thresholds ranged between 2.5 and 12.5 Δ E ab , depending on the color pair, direction, and duration of the transition. In the second experiment, several perceptually different color transitions were compared. The most preferred transitions were a linear transition in CIELab and a linear transition in RGB. The results suggest that it is possible to design a general algorithm for temporal color transitions that is appreciated by human observers, independent of color pair and application.
