A system for adjusting, based on an ambient light level, at least one light effect of a plurality of light effects to be rendered simultaneously by one or more lighting devices, said system comprising: at least one input interface; at least one output interface; and at least one processor configured to: - receive, via said at least one input interface, light sensor data from a light sensor, said light sensor data being indicative of said ambient light level; characterized in that said at least one processor is further configured to: - determine a visibility threshold (235,245), based on said light sensor data, said visibility threshold being indicative of a light intensity level at which light effects are visible at said ambient light level; - determine said plurality of light effects to be rendered by said one or more lighting devices, based on a predetermined dynamic lighting program mapped to a time period, such that the plurality of light effects change over time; - determine that at least one light intensity level of said at least one light effect does not exceed said visibility threshold (235,245); - determine that said at least one light intensity level of said at least one light effect is able to be increased above said visibility threshold (235, 245); - increase, upon said determination that said at least one light intensity level of said at least one light effect is able to be increased above said visibility threshold (235, 245), said at least one light intensity level of said at least one light effect to above said visibility threshold (235,245), wherein the increase of said at least one light intensity level is proportional to said ambient light level, in harmonize said at least one light intensity level with said ambient light level; - control, via said at least one output interface, said one or more lighting devices to render said plurality of light effects, said one or more lighting devices being controlled to render said at least one light effect with said increased at least one light intensity level; and - increase at least one further light intensity level of at least one further light effect of said plurality of light effects on condition of said at least one light intensity level of said at least one light effect being increased in response to said at least one light level of said at least one light effect being below said visibility threshold (235, 245), such that the increase of said at least one further light intensity level of said at least one further light effect is proportional to the increase of said at least one light intensity level of said at least one light effect, in order to harmonize said at least one further light intensity level with said ambient light level. at least one input interface;
