A controller for a lamp, comprising an input terminal for receiving a requested-color-signal representative of a requested-color-value to be provided by the lamp and one or more temperature-values associated with the lamp. The controller includes a full-color-module for providing a full-color-lamp-control-signal for an output terminal; a stabilization-module for providing a stabilized-lamp-control-signal for the output terminal; and a mode controller for comparing the requested-color-value with a threshold value. If the requested-color-value satisfies the threshold value, then the stabilization-module provides the stabilized-lamp-control-signal to the output terminal. If the requested-color-value does not satisfy the threshold value, then the full-color-module provides the full-color-lamp-control-signal to the output terminal. The stabilization-module is configured to: generate stabilized-color-values based on the temperature-values; and provide the stabilized-lamp-control-signal based on the requested-color-value and the stabilized-color-values. The full-color-module is configured to provide the full-color-lamp-control-signal based on the requested-color-value.
